Teamviewer QS cannot open special permissions settings window on Moto one power

Hi,
I tried both TeamViewer host and QS to give access to another device.
Everytime I would open the app, it shows pop-up to grant the "Special Permissions" in the settings window. When I click "open settings" it does not open any setting window and just returns back to the app. This, not able to create the session with other device.. please help.
