You can easily turn off automatic updates. I check the forum before I update. Haven’t had any issues for 10+ years.
Same, never had an issue. And I also skip the latest couple of minor versions most of the time unless there’s a security bugfix. Gives the updates time to bake.
You're correct, but the running gag is that every version released as production is a beta.
It's been awhile since I used Unifi, but regardless of the label they put on their binaries, things felt like beta. That doesn't mean I had issues per se, or things I couldn't work around. But it may be missing things, almost certainly missing promised features, rough around the edges, etc.
