Team Builder Doesn't Save

So yesterday it let me make and upload a team but today when I go back and try to edit the team further it gives me this error and won't let me save or submit it again

Same here.  This started Friday evening for me.  I haven't found anything explaining what's going on.  

I spent a hour making my team builder team and when I want to submit it it says error and I cant even save it and I don't wanna lose all my jerseys. Really ea. 

Same here. What's sucks even worse is that I lost ALL my progress. I dedicated my entire Sunday to making my team & it was all for nothing lol

Same thing here. Worked yesterday. I get this error today. Such a disappointment. Did we all really pay extra for a broken game????

Spent the last 4 hours creating a school and I kept getting an error when trying to save or publish. It eventually ended up sending me back to the home screen which meant all progress was lost. Wake us up when this thing works!

Same issue, and no comment on it in the latest update post.

I've tried creating teams on multiple devices with no success. But now there are 4 team builder attempts that WILL NOT delete from my library. Uploaded images, jerseys, crowds and fields are blank. I cant make any changes that will save and can't delete them. Any help would be greatly appreciated.

Yes, I'm having the same problem.  It's driving me crazy.  

I spent over an hour trying to create a team in team builder. Everything was working fine and I could save my progress throughout the time that I was creating the team. But once I finished the stadium and went to save my team for the final time, I got a spinning circle for about 5 mins and once it was done, everything was gone. Now when I go back to my team, nothing shows and the entire team builder website is shutting down on me.
