Post match Disconnects in Champions and Gauntlet Wins Not Counting

I am experiencing persistent disconnection issues in Ultimate Team that are severely affecting my progress.

I play from Turkey, and my ping usually between 45–60 ms. I accept that ping and continue playing without complaints. However, what is not acceptable is being disconnected after completing matches and having my progress not count.

The main issue:

I finish the match (sometimes I win). After the final whistle or during post-match screens, I get disconnected. The win does not count, rewards are not given. In some cases, it is recorded as a loss. This makes me so mad especially in Champions and Gauntlet, where every match affects rewards.

I tested both Ethernet and wifi same issue. My internet connection remains stable. I reinstalled the game completely no change. Yesterday in Champions, 4 matches were lost due to this issue. Today in Gauntlet, 3 matches disconnected because of connection errors despite winning. I added my connection results at the attachments idk you guys can see but the one match that my connection score was 84/100 i faced the same problem again also i cant see my other  matches it does not show on connection quality report because of my internet :D idk how i can find these matches too im sure someone from ea can see it.

Time, effort, and rewards are being erased because of a server or connection handling issue.

This needs serious investigation. Players should not be penalized in competitive modes due to instability that is not caused by them. Wins must not turn into losses after the match is already completed.
