Hi @asacur. As Damasceno points out please try the Training APK from Github to see if that solves the issue. I am afraid this might be related to the protection embedded in the production App.
To be honest I have never worked with TeamViewer on Android and I tested now for a bit without success as I cannot even connect. I have tested though the remote support with some of the MDMs (as listed here: MDM documentation - How to manage your DHIS2 Android implementation) and it worked well, but these MDM agents run with admin privileges which might be related.
