New packs not detected by game, have tried all standard fixes

Also having this issue and was coming here to report!! I just want to play my game 

Don't uninstall/reinstall any other of your working DLC. It sounds like the same thing that happened to me is happening to you and if you do what I did (full reinstalled) NONE of your DLC will work. Don't have a solution yet but... just a warning so you don't lose everything but the base game like I did.

I'm also having the same issue with an expansion pack I bought today.  I also bought a game pack and stuff pack but haven't got far enough in to see if they are having the same issue as the expansion pack.  My download/add-on manager says they are downloaded, I've restarted the game but when I try to access the new world, it's faded out and says it will be available after it's fully downloaded and restarted.  I've uninstalled, re-installed, restarted and it's still doing the same.  If I access my content through the marketplace it actually shows "deactivated" over the newly purchased expansion pack.  Stupid!

I'm having the exact same issue, none of my packs are showing up in game are are fully installed on EA. 

I just want to playyyyy😢

Did you tried to enable it from the marketplace ( apparently it can be hidden there) 

I figured out what I was doing wrong.  Apparently, you now need to go into Marketplace, look under the "My Collection" tab and choose to 'Manage' (I think that was the option) then it will allow you to select or deselect all of the content you own.  I realized that none of the new content I had just bought was selected or enabled.  I clicked on each one to make sure it had a green checkmark and okay'd the selections. I think I had to re-start? But this time the new DLC's were all there, available and active to use.

I have had the same issues too. I bought 2 expansion packs and neither of them worked. On the EA app it says they are downloaded but when I go into the game I also have the greyed out things and it says it hasn't downloaded. I also tried loads of different things and I even resorted to uninstalling it on steam and redownloading it, which also didn't work. I had a look on reddit and tried my best to follow peoples instructions but nothing they said to do helped. I just want to try out the expansion packs I bought. Any tips or information would be great. 

Thank you. 5 hours of my very limited time waisted troubleshooting this issue. Your post here was the solution. I would not have found the answer on my own because I was looking at the back end or maybe something I have done, Thank you again for taking the time to put this information here.

Yes!!! This was the fix! Thank you!

I'm on a MacBook (hopped over here since I couldn't find any posts on the Mac forum) - but I want to confirm this solved the problem for me as well.
