App Loader Device Connection Failed, Undefined

Thx @daphtdazz for guiding me 😊 sorry that I am not clever enough for finding that by my self. On iPhone 11 you have to tap very close to the end of the screen... I got this now.
But I can not get it connect either.

@daphtdazz @Gordon FYI the log from the app;
