Hello . I ve a Problem . I habe still i phone 7 and the App runs without Problems . But everytime i will be Kicked out of it . I opens it with the Browser Safari . Can i do something Else to Solve the Problem ? Thank you 

Hello, do you get a white screen before beign kicked out? What are you doing before being kicked out?. It may be due to your phone being somewhat old.
