Logos Show Up blank, error 400, jerseys, helmets, stadium will not appear

These are all the issues I’m having with team builder:

1. Logo rarely shows up when I upload, and I know the size is correct. If it does, it never stays uploaded. This happens with new teams I try to create because of my third on the list.

2. When the logo goes blank, so do the helmets, jerseys, stadium, etc. Can’t see anything as nothing pops up.

3. I made it pretty far with one team BEFORE the update but when I went back to edit the players, I tried to save and keep getting “error 400” saying an unknown problem occurred. With this team before the update I was able to edit/save everything.

I have tried every solution that EA has marked as solved but nothing works. Examples are clearing the cache/history/restart browser, enabling pop-ups, using Edge or Firefox instead of chrome. Nothing works and am open to more suggestions. Thanks!
