Summarize your bug I can no longer trade with other Users. Madden21 Gameplay is perfect in every other way, so far as I can tell.
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? I do not know. I'm assuming it has to be a software glitch somewhere, because I was trading normally in every league for 3 months, since I bought the game back in March. I'm basically a daily player.
What happens when the bug occurs? The report under the Things To Do tab will say "(my team) accepted" or "(other team) accepted", but the result will say Declined. Pics attached below. Or, the trade will simply disappear after hitting the "accept" button, and no changes to either roster.
What do you expect to see? I expect to see the picks and players on their new rosters, as happens for everyone else, and has been working perfectly for the last 3 months. 🙂

What is the AMD or Nvidia Model Number of your graphics card? see pic below of the back of the PS4
Enter RAM memory size in GB I don't know. Hopefully the pic of the back of the PS4 below will help you find that number.

Trades between myself and anyone else... Users or CPU... are simply not going through, even when accepted by the other party, or is offered from the other party. Everyone else in all three leagues is trading normally... it's just me. I've quit the league and created a new character. I've quit the league and come back as an entirely new coach. I've tried trades that were INCREDIBLY one-sided, in both directions, as well as some very even trades. I've updated the software. It was just the NFLQC2022 league for the first week, but has now spread to my other 2 leagues, making this even weirder! Today, I deleted the Madden21 game, and reinstalled it. The problem persists. (All the expected explanations, like trade limits in the settings, teams that have played already when the other hasn't, salary cap issues, roster size limit settings, etc have all been accounted for. If this is one of those "did you try plugging it in?" issues, I'll eat my shoe! LOL)
