Seven months. That's the amount of time Ubiquiti's UniFi Controller v6 software has been out (currently on v6.1.71), and it's still riddled with issues. FWIW, I'm still on v5.14.23. I just can't find any burning need to update. Ubiquiti ought to shape up though. The TP-Link Omada is fast becoming the new "UniFi".... in more ways than one.
