With most companies I wouldn't mind.
But with UniFi, Alpha is Beta, and Beta is launched into production.

That's what I saw originally too.  It kept it sitting on the shelf for
months.
It's fixed in their beta software, but not on one of my appliances.

Their switches and WAPs are pretty solid for me.  I have about 150 of each

I've had electricians check power in locations where things died and they
find no issues.  Plus the sites use double-conversion UPS units, so I
highly doubt it's power issues.
