TheRealZap,
I am not sure if you realize this or not but there are a bunch of VERY angry people in this specific forum that have a product they purchased for good money and now it has been rendered practically useless without the main controlling application Amplifi Remote on IOS 9. I am not sure exactly what a Line 6 Expert is supposed to do but you are only fanning the flames and not really helping Line 6 in this case. This specific thread is labeled Amplifi App on iOS 9, not ​Amplifi App on Android. We all realize the Amplifi App runs on Android but we are not Android users. Trust me when I say this, if any of us had an Android device we would have done that long ago.
Your comment "ios9 has been out for 2 weeks... sorry but the timer doesn't start when you decide...." is absolutely the worst thing you could possibly say to this group. Do you even understand why Apple "as well as Microsoft, RedHat, etc, etc..) release beta code to developers (in this case Line 6)?
Well let me tell you it is for this exact predicament that Line 6 is in and so companies don't end up with a product that no longer functions and thus eliminate "VERY angry people". This specific problem was documented in this forum on July 31st with the thread "IOS 9 (beta): Amplifi app shuts down when Bluetooth connection is made". This alone should have had the alarm bells going off in Line 6.
Apple released IOS 9 Beta 1 on June 8th immediately after the keynote at the Apple Worldwide Developers Conference and that my friend is when the timer starts. To be clear the release date was Sept 16th for IOS 9 and the Amplifi App should have been ready.
While I don't have a clue when they actually started or what the issues are they should at least start using the Apple beta testing app TestFlight that allows users the ability to test controlled betas that Line 6 chooses to release to help report issues from their loyal customers. I for one have an old iPhone 5 and would be happy to beta test to provide valuable user based input for their product.
