@David-TP the trial firmware does seem to have improved matters, will there be further updates on this?

  @David-TP apologies for the delay in my reply.

Ive updated all 5 of the M5s with the test firmware. 

Not much of a change really as the android app seems to only find the main AP, not the satelite decos.

On the odd occasion the clients will show for the satelite decos but it will state they are offline, i cant modify the client settings (connection preference, mesh enabled etc...).

All of the nodes are working fine in terms of getting a wifi connection via them, and i can access them all via the web interface (incase you need logs?).

I do have one device (Epson printer) which seems to be dropping connections quite often now.

Cheers.
