I replicated the issue. kinpunpaintVRv1.5Oculus.apk works on my quest 2 but not on quest 1! all joy stick inputs were being ignored!
I have added a new apk kinpunQuest.apk - hopefully that has fixed the problem. Please let me know if this fixes the issue for you.
One note, I had to change the UI controls. A button = select, B button = Back.
Thanks for the feedback!
