Unifi AI hangs at loading spinner?


maybe one of you already discovered the same and have a Tipp for me.
We run several sites with UCKG2 - everything fine. But on one Site I can’t use the WIFI-AI Feature.
If I go to the new Controller Interface > Advanced > Wifi AI it just load the loading spinner and nothing happen.

It is stuck right here:

Weird, not a problem I have encountered. Might want to try backing it up and reloading it.

It seems it was some kind of temporary issue. 24h later nothing changed but it’s working now. weird
