PLEASE FIX

Im updating this review to 4 stars. Ive received a reply from Logitech and Im kind of embarrassed I didnt try this before. A simple reset of both speakers then re-pairing of both has fixed all my problems. Dont know it will help any one else but its worth a try.
Press and hold down the power button and - button at the same time to reset.

As others have pointed out the most recent app update and speaker update has made it impossible to connect multiple mega booms to a single device. One at a time both of my mega booms work but turn them both on at the same time and you get a very poor connection to one of them.
