The issue with the applications disappearing was server related and
should be fixed now. The only bug in V30, I know of at least, is that
wifi sometimes doesn't work correctly.
I already did testing on my network with other devices and my network
was fine. So the only other possible cause would be the quest 2 update.
I know a lot of people who have the same issues. They have done a
factory reset and it didn't help at all.
I spent over a hour troubleshooting my WiFi and I didn't find anything
wrong. Also I tried to contact oculus support but they kept blaming my
router/WiFi and told me to contact my ISP.
