Which Browser Should Be Used With Team Builder?

Im trying to upload custom logos and graphics to the uniform builder, but the items wont upload citing a 400 error. Tried uploading with secondary logo and pants. Using Chrome browser on Win11 machine

@EA_Kent

For those of you who are running into trouble using the Team Builder, would you mind sharing a bit more info?

Which browser(s) have you tried using? Chrome and Firefox
Are you getting a specific error message? "Error 400"
Where are you running into problems? Any page/section of teambuilder.
Are you not able to enter the Team Builder at all? Yes.
Do you run into a problem when you're trying to edit/save something? Only when trying to save anything. Literally any thing. Nothing will save. There was no issue until the first patch on Saturday of last week saved fine before that.

@EA_Kent I've tried pretty much every browser I have, the majority is super slow, like chrome, edge and opera GX, but when I got to firefox today(7/23) it's been fast, I had no troubles on getting into it at all, the problem is that when I try to upload my own logo the load is infinite, also there are no previews for uniforms and field design so I can't see what I'm doing, all of this that I'm pointing out has occured on firefox, chrome and edge are super slow so I can't do anything besides waiting for it to respond for about 10 minutes every stage and no previews at all also, and opera GX is giving me the error 400 everytime I try to get in since yesterday

At home, I have used Safari and Chrome on an older but powerful iMac Desktop.  Safari is a total no-go.  Chrome was working great initially (Friday, 7/19) but within the last couple days (7/22-7/23) I have been unable to upload logos.  I also attempted to submit my draft team and received the 400 error and was unable to submit.

On my work PC today (7/23), I used the current version of MS Edge.  When I attempted to submit my team, the site just spun.  It never loaded, just kept spinning while trying to generate logos. Some site images are also failing to load.  The uniform preview images, some of the header images, etc.

@EA_Kent I've Gotten a few teams finished... My major issues with the SITE are as follows:

- Since launch, I've got one computer (my work comp) that just cannot upload pics to the site at all... I'm about to check firewall here in a sec, but it'll either freeze, or upload the pic and not make it visible..  (i5 series 4 laptop, 8 GBram, HARDWIRED connection)  HOWEVER, my slightly later model i5 series 5 laptop with 8GB running Linux Mint WAS able to create upload and submit 6 teams and changes, with spotty connectivity along the way.. It's a pain as I have to email myself all the files i create on my work comp.  (tried this with both Firefox and FALKON on the linux  computers AND ms edge and firefox on the PCs, both computers completely up to date both in the browsers and OS)

-Currently (358pm eastern on Tues), even the small changes I'll make to a new team will just sit and spin the wheel/ freeze on LOGOS.  it seems like anything involving a save or an upload it freezing the site on my side (even from the linux comp i've had all the luck with...) Make a change and try to save it, and like dude said earlier, it sits and swirls on GENERATING TEAM LOGOS

-Inputs, when working, are taking INCREDIBLY long... any accidental click of the mouse can be interpreted as me messing with a slide, and It's forced me to use some REALLY low decimal points for fine adjustments

-2nd custom images on the field don't show when you apply them.  A workaround allows us to use an EXISTING logo custom, apply it where you want, go back and change it to your custom image and then re-sizing it DOES work, but it's an extra 5 mins total per team creation if you're getting cute with the field.

IN GAME:
-Uniform selection lighting works for Uniforms, is terrible for helmets and it makes it hard to check our work.. We have to go launch a game WELL LIT in an outdoor stadium (Sorry, 'Cuse fans...😉) to see if the chrome helmet we've setup looks weird that way... (sorry, i'm a*al like that) Chrome helmets/ accessories look EXTREMELY dark in this menu.  Not a big deal for in game BUT it does add tons of extra time

- after that INGAME complaint, I'ma leave it alone as it's the best FEELING football game i've ever played BUT

- I accidentally ticked UNSHARE in-game on a team i setup, as the menu gets wide and wonky with more than 5 teams, and the pop up for DOWNLOAD or UNSHARE is hard to see...  That team is now GONE from MY TEAMS on the TB site and i gotta set the South Harmon Sandwiches up again... there needs to be a confirm for unsharing, or maybe just make that button say DELETE to demonstrate the impact just unsharing will have.... The team logos and etc stay on the console, and if you launch the game or check uniforms with and unshared team, ncaa25 crashes...

that's all i got now... I'ma whoop my son and prolly upload some screenshots soon... but yea... in game things are working wonderful for a new release, the site is slow OR should be converted to a standalone windows/ mac/ linux release that'll upload to the site upon completion.

thanks!
