Fc mobile bug

There’s is a bug when I play the icon chronicles(specifically Roberto Carlos, vs besiktas) and when I finish the match right before the results it says connection error”you are not connected to the internet and we cannot send the match results. Do you wish to try again?” I already tried uninstalling and I have internet connection(a pretty good one) and it’s only that match, others are normal.This has been going on for a week and I really want Roberto Carlos🙏🏿🙏🏿🙏🏿😭
