Yes, my BLUE still on 8.0 B5, went idle today. Reset was all it took. Both my RED and BLUE would stop sending with 8.1
I've held off on updating to 8.1-b1 though Tobi thinks the problems are minimized.... this may be a server issue also, since this is the only "idle" I've had on 8.0b5 since day one with it ... I'd go ahead and mention in in the BT FIRMWARE THREAD if it happens again....
