I bought the 150 yesterday and have the same problem. The Bluetooth connection is up as I can play music from my iPhone however after changing a few effects or selecting different amps or cabinets the change is not being applied to the amp. If I close and restart the app it will work again until I make a few changes. I have the same problem using an iPhone and iPad both running the current ios. I'm fairly confident this will be resolved with an update at some point so I'm leaning towards keeping the amp. It's just a little frustrating. Another thing that irritates me is when you select a song from your library it starts playing immediately, before you even get a list of tones. I have to tap pause two time to stop the music. I would prefer to try some of the tones first and start the song when I'm ready.
