I upgraded to it yesterday and noticed several bugs, two of which are quite annoying:
1. The Touch ID feature is not functioning perfectly. It fails to detect fingerprints after only two unsuccessful attempts, whereas it used to allow around 5 fingerprint retries before requesting a password.
2. Today, when I locked my computer and tried to log in to my main account, it displayed the profile picture of the standard account and the name 'main account.' I only realized this after restarting macOS.
Occasionally, when launching new apps, the screen experiences a brief glitch.
It appears that there may not have been enough testing done on Sonoma.
