I did the install on 2 Axiom Airs, and now the multi-room capability does not work at all for me. Also, from the app I used to be able to switch control from one AA to another by clicking on the AA image on the bottom of the screen. Now, when I do that I get the "spinning circle of death" and never get connected. It is very difficult to control AAs from the app if you cannot switch from one to another.

Is there any way to get back to the previous release?
