I have an Arc, four Ones (each in a different room) and a Move. Over the years, I’ve had occasional problems with speakers dropping out, but never sustained or consistent. Since adding a Move to my system a few weeks ago, the problem has been nearly constant. If playing to more than one room at a time, speakers regularly cut in and out, frequently enough that the system is becoming unusable. Some speakers do this more than others, but it happens with all of them, with no discernible pattern. This happens whether playing via a streaming service (usually but not exclusively Spotify) or via my local Music Library.

The Move integration may be coincidental, but the problems have coincided with its addition.
