I've found the main problem is when on a DFS channel and doing something real-time -- a Zoom/Skype call, for instance. Very noticeable then.

Also, don't use hidden SSIDs on a DFS channel: https://badfi.com/blog/2016/2/15/yet-another-reason-avoid-us...

The correction at the bottom of the article you linked indicates it's not that much of as problem to use hidden SSIDs onn DFS. The 100ms beacon interval latency mentioned isn't going to be much of a problem with how slow and unresponsive the WiFi stack on most devices is anyway.

Hidden SSIDs use beacon frames too, as far as I remember. They just don‘t broadcast their SSID in it, but clients can see them and then interrogate them ("are you part of SSID xyz?").

You didn’t read the article did you. It makes no difference.
