About a year ago, I asked in these forums how to restrict some devices to certain APs, and learned about SSID Overrides, which has worked perfectly for my needs.
Now, I've upgraded to Omada SDN Software Controller 4.1.5, and things are going well, except that I can no longer successfully create SSID Overrides.
Under Devices > Config > WLANs, when I click the Edit button next to one of my existing SSIDs (in the Default WLAN group), I do find the expected interface:
If I then turn on SSID Override, enter an SSID name, provide a password, and click Save, nothing at all happens (that is, the SSID Override interface remains, and if I navigate elsewhere and return, my changes are lost).
Interestingly, if I do the same but do not type a new password, then when I click Save I'm returned to Devices > Config > WLANs as I'd expect, and my new override does appear in the Overrides column as I'd expect, but...after 2-3 seconds, it vanishes.
Any thoughts on what I can do to convince Omada Software Controller 4.1.5 to accept an SSID Override?
