Starting situation
Play:3 and One grouped, playing music. Play:3 is connected to the network through ethernet cable, One through 2.4Ghz wireless.
Action
Stopped music, unplugged One.
Problem
When plugging One back in, it directly shows up as grouped with the same Play:3 as before unplugging. The One does not play any music but the Play:3 does. When trying to ungroup, the app briefly 'thinks' and then gives an error. Unable to connect with device. Try again later.
Other info
Play:3 works as it should, both with and without being grouped with the One.
Tried power cycling devices, as well as the router.
