Was playing on a Google Pixel Android. Second game in an Arena run. After my first turn I was waiting a long time for my opponent to play. Realised after a minute that nothing was happening in the game even though it looked like it was still active. Killed the game and started again but had lost my match.
This is happening regulary, about once every 10 or so games. If it happens on my turn I know straight away and can kill and restart, if it happens on my opponents turn I usually don’t have enough time left to restart the game before losing a turn or failing to reconnect to the match.
