Endless arena turn

Occasionally I have to lose arena games because my opponent’s turn has no end. I can clearly see that he hovers mouse over his cards and arrows appear randomly on the screen. i can stay in this stalemate for hours and the same thing seems to happen to my opponent. however, a restart always results in a lose. I wonder what my opponent gets. it is very unpleasant to lose like this. from smartphone it doesn’t seem to happen. also internet works perfectly when it happens. I’ve never had this kind of problem in traditional arenas but it’s already the second time it happens with arenas that mix two heroes. Right now I’m scared to keep playing and throw away what might be good results

you lose connection to server. That’s why you don’t see what cards the opponent is playing, but only arrows. It’s always a connection loss on your part and never anything else. That’s why 99% other players don’t face this problem
