Can't Access Ultimate Team Lineup At All

Just to give a little backstory, just to help further explain my issue. On July 7th, I first opened Ultimate Team and opened all the pre-order content and after obtaining players through all the pre-order packs, I was able to access the my lineup screen without any issues and was able to make any changes as needed. On July 8th however, once I obtained more cards after completing two games in the Solos (Freshman Season) game mode,  I started to quick sell any extra cards that I didn't want to keep and was able to sell them without any issues. After I started to quick sell any cards, any time after this when I try to access my item binder or my lineup in any way imaginable I get kicked from that screen and receive an error code stating "Our servers cannot process your request at this time. Please try again later." Lastly, I have tried restarting my console, deleting/reinstalling the game, and everything else possible to see if that would fix the issue and I have gotten nowhere. Hopefully someone is able to help me with this issue because its aggravating when I pre order the game to be able to play it earlier then everybody else only to incur an issue like this that prevents me from playing this game mode in its entirety. Thank you so much for looking into this and hopefully somebody in this forum or someone from EA will be able to help me with my issue.
