Impossible to get support for OneDrive for Android

Dear Microsoft OneDrive Team 

It seems impossible to get reactive hands on support for OneDrive for Android App.

You cannot open a support ticket via the support web pages specificially for the Android App as there is no category. 

The "report a problem" feature in the Android app is not helpful as no one can contact you and you cannot leave contact data 

You cannot upload Videos or Screenshots other than the one automatically taken but this does not show the issue. 

How can we solve this?
