Move and Roam continually disconnecting from Sonos App

I have a system which includes a pair of Sonos Ones and a Beam all working together in one room, and older Play3 in another room and finally a Roam and a Move in the final room.

I work from home and I typically play the Roam and Move together as one to listen to during the day,

I previously used Apple Music app and then selected the airplay option to connect to those two together. However they wouldnt always connect despite always showing in the list of speakers. Just says fails to connect.

So I ended up switching to using the Sonos app, selecting another room (usually the play3 as only that and the Ones would appear via the app), going to apple music and starting a track. I then would press the room grouping option and wait for the move and roam to appear. Eventually they would, talking minutes. THen deselect the room i didnt want and off i go.

Sometimes this would last all day, but if i a playlist ended I then go and select another via apple music (through the sonos app) it would say cant add tracks, because it had lost the speakers (even though it had only just fnished playing). its as though a certain time elapses and they lose connectivity to the app.

So then have to go through the whole process again, but always have to end the sonos app first.

Its a pain. nothing has changed with my network at home and its just getting worse, now bored of it.

Another thing, if all the above has happened and Ive lost the connectivity, i can then press the play button on the roam and that and the move start playing the last playlist again from the start?! but they dont show up on the app. So yes i can listen again but have no way of changing it until i repeat the whole process above.

No longer seems a seamless system.
