App not showing up on Oculus Go - build from Unity 2019

My project was building fine in 2018 and showing up on my Go under “unknown sources”.

My project builds fine in 2019 and it says it gets installed but it no longer shows up under “unknown sources” or anywhere else that I can see.

I can uninstall using adb - so it’s there apparently, but where, is the question.

thanks

Update the project to 2019.2
and remove oculus sdk in XR setting of player settings
Turn off VR supported in XR settings
than turn on VR supported in XR settings
than again select oculus SDK from list
