How can I tell if my custom tapestry imported into my game?

One way of knowing is when you are suddenly presented to your old character form Kirkwall.

The game asks you if you'd like to import the looks of your old hero or use a custom one. If you chose custom you will notice that this character will look similar to you old hero. Maybe not quite but fairly. Just do a few adjustments. You have this option when your hero is presented. The character creation screen will be available for this.

Lovely, I did everything as asked. I verifed my account was synced. I made sure it said it synced with the keep but here I am 100hrs in and all my work on the tapestry, all the decision in the previous 2 games are for naught.

This whole auto sync and hope for the best and try and find out many hours into the game is garbage. How hard would it been to confirm what was being imported or exported or just to have a spot to verify what tapesty had been imported and was being used.

This whole thing has really just taken the wind out of my sails. Continuing my game in the world I crafted was the biggest draw for me in this game and it's shot because of the whole auto import no real way to know if it worked since EVERYTHING said it synced/exported, etc but there was no way to really confirm this until much later into the game to see if this was really the case...

First of all. Try to read manuals for Dragon Age Keep. Second, it is say that it synchronized, when it is exported the World setting FROM your previous 2 DA games. To import your World to the DAI, you need to open left side menu in the Dragon Age Keep, set YOUR World as active one and only then manually press the button to import current World settings to the DAI. It will be confirmed if the image of monitor would have a green check mark.

And of course, when you start a new game, the DAI asks you IF you want to import the current World settings from the Dragon Age Keep.
And for the game, if you notice difference from your World ONLY after 100 hours of gameplay, you sure did not paid any attention to the surroundings. Since all characters speak about bits of previous events here and there all the time. Not to tell that Varik can tell you about what happened to the heroes of the DA II right at the start if you speak to him in Heaven. There was plenty of hints, you just not paid attention.

I read and did everything on the keep. My custom tapestry has been set and been active since before I started my first game, I verified on the keep that the proper accounts were associated with my corresponding console accounts and the game did ask if I wanted to import my current world setting. I was painfully careful about this as I done this all previously on the 360 and was starting over on the PS4 becuse performance on the 360 was so poor.

Your comments about paying attention to the settings and picking up on all the hints are fallacious as you have no way to know what Varric is supposed to say or not say so short of being a developer you have no way of know these things. The backgrounds in the default world state for the characters in DA2 sync up with my playthrough.

All this would've been easilly avoided by simply having on the options>dragon age keep section to say that the custom world state was imported and or the name being used. Instead when you select in game it says to go to dragon age keep and set up a world state to sync. VERY poorly done. If you really think the way it set up and the needless complexity and total lack of being able to confirm if it has been imported or not until many HOURS of play time. Go back and read your own first paragraph and ask yourself if there was a better way than the endless sync, set active , press to import, confirmation being a small green check mark on an icon that is not very obvious and nothing even points you to it. By the way I did all this and it just didn't work. If you go look at the many articles on the intricasies of the keep you will find there are problem with some of the Origin accounts not syncing properly and the solution is to start over, share your world state and then reimport it. (no joke).

I Agree the Tapestry is the biggest BS I have ever had to deal with. 6 Hours now, and still have not gotten a new game started.

And I built my Tapestry 9 months ago.. Its sickening !

I am having a similar problem, specifically with Hawke, as I'll explain below.

I created my Tapestry before ever obtaining a copy of Inquisition. I set up the Tapestry because it looked really cool and was fun to choose all the little options to make things unique.

Now that I've been playing Inquisition (about 20 or so hours in I think?) I'm at Skyhold at and the point where I talk to Varric to summon Hawke... and Hawke appears in the "Customize Hawke" window as a male, whereas Hawke is clearly female in my Keep. Talking to people from EA produces the same scripted answer of "post in the forums" and pray to the damn Maker you get a response. I can live with male Hawke but it breaks my immersion because my Hawke that I created in the Keep is how I imagined them - a badass female rogue who romanced Fenris. Not a male character who appears to have the default backstory. 

I also encountered another lovely error where the "Champions of the Just" quest line was completely greyed out and 'hidden' in my Tapestry when I went to fix it after spotting that my Inquisitor had apparently sided with the mages whereas in game I sided with templars. I had to click around inside the quests a few times and that finally resolved itself. I've re-imported, reworked, redone all I can in Tapestry and with the game. I play on PS4 so I don't know if this is unique to the PS4 version or what. It's really * annoying though. 

@Dragonessa0007 Unfortunately, once you start the game, you can't make any changes in the tapestry and have those changes affect the game you're currently playing (you can only upload a custom world state during character creation). When you upload a custom world state to the game during character creation, check the date and time of the custom world state to ensure they match the one you have saved in the keep.

The data that gets uploaded to the Keep as you play Inquisition doesn't go to your editable state tapestry, it goes to 'playthrough states', which can only be edited or looked at if you copy them over to editable states. You can find playthrough states by going to world states and clicking the right arrow on the side, or selecting playthrough states from the dropdown menu. These are also rather pointless at the moment, they'll only be used when Dragon Age 4 comes out, and just like now we'll be able to edit the tapestry as much as we want before uploading it to the game.

It is really annoying when your world state doesn't upload correctly, especially if it's the sort of state where you don't find out until you get to Skyhold that it's wrong. Unfortunately your options are to continue with your current character or start a new game. Sorry.
