Hand tracking outdoors

Ok, just a little update on this topic.

Since I made the original post, we have switched a bit away from using the Quest Pro and we are now mainly using the Quest 3 instead.
We were also initially experiencing some flickering of the hand tracking on the Quest 3 when using our app outdoors in bright conditions. But after some testing, we figured out that it seemed to be caused by our setting of hand tracking frequency which was set to high.

First we couldn't figure out why the resulting AndroidManifest.xml in the built apk would still have com.oculus.handtracking.frequency set to HIGH even when changing the settings on the OVRManager to LOW. But that was due to the fact that the custom AndroidManifest.xml we had in Assets/Plugins/Android still had that setting (we had previously created it by choosing the menu Oculus->Tools->Create store-compatible AndroidManifest.xml). But either deleting the custom AndroidManifest.xml or re-creating it after the changed setting of hand tracking frequency solved that problem. 

With the hand tracking frequency set to LOW in the apk's AndroidManifest.xml, or not set at all, we don't experience the hand tracking flicker. And we don't really notice any difference in the hand tracking responsiveness - at least in our use of it.

An extra interesting finding: there is a developer setting on the Quest (in System/Developer) called Hand Tracking Frequency Override, and if we set that to High, we see the hand tracking flickering even in the operating system menus (outdoors in bright conditions).
