I’m having problems grouping my Sonos amp with Sonos one speaker. I’m using flow card join another players group.

When testing it I’m getting an error “Cannot read property ‘id’ of undefined”. Have you guys experienced same error? I guess it should be possible to group an amp with a one speaker…

Thanks
