Hi! The Update to 15.2.2 kind of makes the app not working properly any more. We are using 6 iPhone 6 with iOS 10 The Symtoms are the same on both Devices - answering a call from the lockscreen is fine, but calls sometimes get disconnected after about 20-30 seconds. - opening the 3cx app while in a call from the lockscreen makes the app crash... so phone system functions are kind of obsolete now... why even using the software then?... - after pressing anything in the app, the app is "loading" something (see a loading icon in the status bar) for about 30-60 seconds.
