We have been experiencing a problem with the Sonos spontaneously stops working then reappearing (sometimes). After many hours of looking at routers WiFi etc etc we think we found the problem.
I have 2021 iPad Air, my partner has the older iPad we only have the issue when using my iPad iPadOS 14.4.2. No issues with older iOS 12.5.2
so before you pull your hair out with WiFi settings etc this may solve your issue.
equ- Play 5 1st generation And Connect to my amp.
Sonos - please sort thanks.
