Sonos era 100 connection failing

[RobinJ2909]

I have 2 Sonis Era 100 speakers either side of my sky glass. Unfortunately they just won't stay connected with Bluetooth. I have tried everything suggested so far but having zero success. Any help appreciated

@RobinJ2909 You may wish to look at the sky Glass area of the Forum, nothing to do with BB as NO Bluetooth used by a hub!
