Since 2 days i have these disconnects. It seems like they are related to certain cards. For example just as im playing, every time i play Pen Flinger, the game gets stuck for a while, until the message "you have been disconnected" and "reconnecting" pops up and then i can continue.
Im playing on PC, never had that problem. Yesterday i had the same issue with another card, but cant remeber which it was.
I disconnect fairly regularly on Android and ChromeOS (on WiFi and mobile data).
It's rather frustrating because instead of reconnecting instantaneously, it often takes the game 15 seconds, 30 seconds, or perhaps longer to reconnect. Closing and reopening the app also takes a bizarrely long time.
If you've missed a turn or two, you might as well concede the game.
Having tested different hardware and networks, I can only think it's a HS problem.
