We’ve had a UEBoom 2 for 18 months and just added a UERoll to the family..
Excited about the pairing feature we discovered that the Roll moddles don’t pair with the various Boom models!!

Vigorous google searches show that they once use to, but no more.

Why? What reason could Logitech have to seperate these 2 family of speakers - they even have their own app!

One site suggested rolling back the firmware, but I can’t find any sources offering earlier versions, of the tech support on how to install if I did.

Any advice?

Sorry UE - your get fail from me.
