Sometimes it takes a minute to think, then i can play again. Often times it just times out and sits there spinning forever until I force quit the game. Does not happen on my phone.

 

Thank you

This is well known as the "bag lag", it happens if you did not click on your bag in battle,

after you spent quite some time in game(even when you are not in battle... )

 

I found out that if you click on the bag(in battle) once every few minutes, the "bag lag" will be shorten.
