Hi rick7525. I'm using an iphone6, and just like sgapper says, stays connected and streams music, but nothing more. Also, I've checked out the app store reviews and since the update, most are negative, citing that the only improvement is that it doesn't crash.
You say that the app stays connected on your iphone, but can you hear any difference when you load tones or edit? If so, could you let us know what steps you took when installing, turning on the amp, connecting, etc,.?
