I think you might be fighting a feature here, as in the controller might be 'optimising' your client performance by connecting them to the lowest latency AP.  You might want to disable that kind of functionality in the OC200 and see if it starts behaving simply.

 

You can absolutely change the SSIDs on meshed APs...I do exactly that.  In fact, you can build a custom SSID profile for each AP, with one SSID unique to the location and another that is common across all for devices that prefer to be mobile.  If you do this, you'd probably want to leave the 'fast roaming' stuff enabled (don't disable as above) to ensure seamless handoffs when smartphones are moving about, but fixed devices like streaming boxes, cameras, thermostats can join their unique SSIDs.

Create, or create and apply?

So you created a new WLAN profile and applied it to one or more APs? In theory your meshed APs should only 'isolate' when there's been a change in the 5Ghz band, and only when channels change. My recommendation is to fix the 5Ghz channel used by your root mesh APs (the wired ones) because if those change, say because you cause the radios to reload a new profile which kicked off the 'Auto' channel feature again, you WILL isolate APs downstream. It will take some time for them to give up, reset, scan channels, find their new master again....etc etc. If you only have 1 wired root AP in your mesh and you live in NA, try fixing it at ch149.

Agreed that is super-odd, I have had almost exactly the same setup for the last 2 years and the only time I ever had to climb a pole to reset an AP was when I had to reinstall my software controller without defaulting everything first...you do that exactly once and then never forget!  I've suffered the occasional 'isolation' alert, but that was during horrible weather at the farthest AP and the signal was absolutely dropping out and yet it always auto-recovered once things dried up a bit (I changed the topology last summer to resolve this)

 

In the meantime, unless there's a reason for it, I would suggest swapping the 610 and one 225 and making the latter your wired AP (or just outright replacing it with a 225), it is possible that there's some firmware interaction going on between the newer firmware in the 610 and the much older firmware in our 225's.  If you need the Wifi6 or other feature of the 610 it can share the mount location (you could inject power locally and feed it from the LAN port of the new 225).  It's a $100 g4mble that might just stabilize things, if not PM me...I'd make an offer :)
