Get a better connection. It is obviously not fine.
I usually play via a cable connection and have never lost a game owed to a disconnect like what you describe.
Sometimes I have tried to play via wifi over my phone, which is wifi coming off the same cable connection and there are more problems. When you use wifi, your phone decides whether downloading the latest app upgrade is more important to you than the next chess move.
All my phone and internet signals are fine.
It never happens when i’m loosing.
I know i’m not the only one
Any suggestions???
