it got fixed for like >80-90% of the players
whoever still has problems - the problem probably lies in either your pc (hardware) or your updates on chrome and/or other programms (software)
if you checked everything, you might just want to send a report ticket (open the game on chrome, it’s beside “youtube”-button [not the [f] ] )
or on the web — google -> warchest -> support -> submit a request
and write down the important information of your pc (hardware) and the version of your chrome. if any information is missing, they will ask you for it. if they find the problem, they will tell you.
may take several hours up to a weak (they’ve got a lot to do)
it, took ~2days for my request.
