TeamViewer QS - repeatable error message on iOS 12.0.0 (Beta v3)

Hello,

Just started testing the latest iOS Beta version (Release 3) for my company.  TeamViewer QS seems to to be fully functional.. however, every time the screen broadcast is stopped, the iOS device throws the error below.

(Note: I am using the most recent version of TV QS in the public Apple Store (v13.2.110220 QS).
