Speakers play from iPhone, but not iPad
For years I have streamed SirusXM music (or my Apple/iTunes Music Library) to all of my Sonos speakers, mostly Play5 and Roam, but now they can only be played from my iPhone 15 to the speakers, My iPad sees the speakers but the sound does not come out of the speakers and it eventually gives up and stops trying. This problem appeared in the last 1-4 weeks.
All Sonos speakers have the current firmware.
All Apple devices are using the current iOS or iPadOS.
No recent network hardware changes.
All speakers are accessed via wifi & AirPlay. No ethernet involved.
