I have sideloaded games/apps onto my Oculus Quest 2 headset and they appear in my list under "Unknown Sources", but then a few hours later or maybe it's after I'm done for the day and power off and then power back on my headset the next time I want to play and they are not there; the title Unknown Sources isn't even there in the drop down list.

Also, why do the games/apps that I have loaded onto my headset under my account or profile do not share with the other account/profile I have set up on the same headset? The titles from the Oculus store do because I have the "app sharing" enabled.
