I have a Galaxy s10e running Android V9. I am able to connect to Portal applications, but screen gestures - pan, pinch zoom do not work. Double tap will zoom. All other functionality is there. The application also behaves the same on a Galaxy Note8 Android V9. So far, all other devices (including a Tablet running V9) work fine.
I have removed the screen protector and turned up screen touch sensitivity. No change.
The Galaxy s10e works fine with AGOL Apps and Google maps.
Anyone else experience this? Any ideas?
