So on mobile the glitch happens after watching an ad, closing screen and opening again, viewing tasks and on alot of other stuff i cant remember...
This has been a problem for a very long time and i cant understand why it hasnt been fixed. Its so frustarating.

@ツgooby It happens to me as well but very rarely. I usually close it and open it again

@amogh-sai Yeah it fixes after killing the app and opening again but it frustrating to wait on the loading screen and for example in the league battles after reviving dragon by watching an ad you cant see the abilities. It would also be nice to be able to swap between the game and guides on the internet.

@ツgooby Try if clearing cache helps.

@bettina-löffler Ok, after clearing 3GB of cache i can now turn off the screen and when i come back it works. "View tasks" doesnt work and im not sure about ads, i will let you know if i can watch ads without problems. Thank you.

Edit1: Cant leave the game using home button and come back without the glitch.
Edit2: Ads dont work eather

@ツgooby Sometimes it is one add that doesnt work proper that screws everything. If you still have that issue you could reset you ad ID in google settings. That will give you different adds. About tasks... in some countries they are not allowed.
