I've changed every setting recommended in the forums to resolve this and keyboard (not touch mouse or switching screen etc) input isn't working.
Toggled UDP settings, uninstalled and reinstalled TeamViewer host on computer and remote access app on phone, tried connecting and using keyboard input on 3 different mobile devices, reset keyboard settings/cache on main mobile devices, checked language settings/keyboard layout match, installed an alternative keyboard app on mobile devices, ensure input options are enabled on host computer, etc
Issue has arose out of nowhere the last week or so and if anyone has ANYTHING in terms of tips etc to resolve I'd be greatful for the assist!
Many thanks in advance!
