I was considering replacing my AP AC Lite with whatever 6E equivalent comes out when 6E is approved. I considered picking up a NanoHD for the extra MIMO speeds, but in the meantime I keep seeing problems with reliability, the 6.x Unifi version, UDM needing to be rebooted, etc.

Even if Ubiquiti was as good as it was pre-2019, if they pulled this advertising stunt then I'd not consider upgrading. There's now no chance I'll be sticking with Ubiquiti for my 6E upgrade.
