AP6 420E Central setup painful, also will logs indicate DFS detections?

OBSERVATIOBN: Love the new AP6 420E, but man was that a painful experience. It accesses multiple sites -- apparently using QUIC -- so had to disable SSL decryption entirely and QUIC prevention entirely, and other stuff as I flailed around trying to get it to register with Central over what was originally a lunch break. (Yes, not enough time set aside on my part.)

There really should be instructions about the kinds of issues that will interfere with it registering -- and also with it updating and logging.

QUESTION: does the AP6 do DFS detection on an ongoing basis, and is this visible in the logs? The Gather Logs option works very well and I was able to look through two different logs, but nothing leaped out at me as indicating any kind of DFS conflict. (I'm thinking of jumping to a DFS channel to avoid some local congestion for the majority of my equipment that has 5GHz but not (yet) 6 GHz. Channels 52-65 looks very tempting, but...

Don't get me wrong, I am glad I purchased it: it runs well, has nice features, and will really come into its own as the equipment upgrade cycle brings in 6GHz-capable devices. But man was the Central registration painful.
