I don't actually know what a loss by desist is, but, According to Britannica, " A player who initiates a sequence of repetitions must desist or will forfeit the game. "
Desist

Please urgent solution, many people have this problem.... simply doesn't matter if I'm playing a good game or not. Many times it stops suddenly and gives the victory to my opponent after freezing time. It no longer depends on playing well or badly or beating the opponent. It's a roulette. The worst thing is Lately I can't play any game normally anymore. When it freezes you have to exit the game and come back only to discover that by default the game is considered lost and the points were deducted as a defeat. How easy it is that my rivals are winning XD. It's like a hidden camera joke XDXDXD....I clarify that all Android functions work well on various devices and websites in my home...The only way to continue the game is to close and open again and that generates by default the ending already explained.
Given your description, I assume you lost connection which makes it look like your opponent's time is running, but in reality, your time is running and if you don't regain connection quickly, you automatically forfeit the game.

I can't play normally on chess.com from many hours ago The game simply freezes and appear advise telling me that I lose by desist... very frustrating. I can play normally on all other websites.My pountation is falling down in each new try.
