I mentioned some strange things under IOS 11 in contrast to IOS 10. Under my device with IOS 10.3.3, my app works fine and all the animations are the same as always. On my iPhone6s with 11.2 (beta), there are strange animations in the customlistview. Sometimes, the app will stop working and I have a simple global boolean-variable, which is not able to hold the entry. I made a test with another global variable and set it to true, if the page3 is open. It will be false, if the page3 disapperars. Than, I read this in Application_remotenotification, but the boolean is always true, even if the the page3 had disappeared. The only position, I set this variable to true is when page3 appears. Without a few things , this version had run normaly on this device with 11.2. before yesterday. When I see the app working, it seems, that more than one variables changes the enties uncontrollably.... Did someone mentioned something similar?
