I have done, I'm also on the public beta 12.2 and reported again. I have tried it with and without docks (and different drives) and it still ejects. I had webcam issues on an early monterey beta and apple did get back in touch with me, but that has since been resolved.
12.1 broke search and filters in Outlook (version 16.56). I have reindexed, etc. to no avail. Its is a major bug if you rely on these features. I have had to resort to webmail!
But no one helps any way?
I've complained
Ever since I upgraded to macOS 12 my docking station is not working (won't recognise any USB devices) and the same with USB hubs. Everything worked perfectly fine in Big Sur and still works perfectly on my Windows PCs.
Image load time in Maps. It takes now to load images on my iMac 2020 approx 10s.
I am on high speed internet (cable)
Notes
iCloud sync isn't working occasionally between devices with shared notes
if the issue happens, notes are delivered to the other device at all or with very long delay
iCloud sync isn't working on some notes between devices logged under the same
Music
Apple music not loading artist pictures / covers when song changes while listening to Radio
this happens also occasionally and mostly when the Music app is not closed and iMac goes to sleep due to inactivity
After resuming back, I do not see the artist pictures / covers not changing according the song that is currently playing
Side panel notification performance
I have noticed stuttering experience when expanding notifications in the side panel that are collapsed under one app. For example Whatsapp notification list stutters when expanding
Most of these are mostly cosmetic issues and other than this, I have mostly positive experiences using 12.1. For me personally is Monterey better experience then was Big Sur in its early releases.
