We’re sorry for the subpar experience. We’re currently continuing to work through the errors and crashes we’re logging through our new backend error reporting and we hope that we can get some of these Quest crashes fixed soon.
With regards to your party member who got kicked out multiple times, I would let them know to look into the home WiFi bands issue described here: Oculus Quest FAQ and Common Issues/Workarounds as that sounds more likely with that frequency. We know that’s helped quite a few people in the past if that is the situation.
