I was flying and suddenly heard a stall alert. It was completely impossible，I was flying at 33,000ft at M85. I see a prompt saying my account is logged in on another device, but I never gave my account to others. I used to play this game on my old phone, and I have experienced this situation (I no longer use that phone and it is off). No matter what you do after log on another device, you cannot save your plane. Facebook is generally difficult to be stolen. Even if it is stolen, you must log in to the IF game before that happens. So I wonder if it should be caused by some other reason. I don’t know if you have encountered it before.
This has your answer :)
