wifi problem with android app

Moyners

Hello everyone, I cannot connect with my teamviewer quick support android app using wifi. I works fine though with mobile cell internet. Additionally the quick support of my desktop computer (windows 7) using the same network works fine, so it cannot be a port problem.

Can anyone please help me? I am using a huawei tablet with android 8.0 and quick support version 14.0.33. the latest huawei addon has also been installed.

Thx in advance and greetings from germany.

Just discovered that the tablet's display is OK as long as the tablet is in landscape orientation.

I'm trying to assist with an app that insists on portrait mode, so as soon as I switch to this app, the screen display goes back to portrait and my teamviewer remote control display gets scrambled.
