So,
A user story: I once thought I'd be editing my favourite sound a bit or maybe download a new one...
I hadn't updated my iOS (iPad2 retina) until now to 9.2. I started the remote app, then went for the update for Line6 Amplifi FX100 firmware since it noted that an update would be available. Right, so my iPad app was already the new one as it should have been before updating the actual Amplifi device. Once it had started the update a note saying "restart Amplifi FX100 device to continue update process" (or something similar) and I was supid enough to do so. After that I have never got to stay in the remote app for more than 5 seconds until it crashes and simultaneously I can see the BT connection dropping from the Amplifi FX100. And I haven't since.
Step 2 (Fine! So that's how it is?) I then went and updated my FX100 with the PC upgrade usb -tool, calibrated the pedal and ran the factory reset. Then I took the iPad and "forgot the device" in the BT settings, made sure I hadn't the remote app running, turned BT back on, re-paired the iPad with the Amplifi FX100 and started the app... yup, iPad and its remote app goes lollipop up after 5 seconds or so.
Step 3. Go to line6.com forums to read about the new iOS9.2 compatible app. Well... The remote app keeps crashing every time I pair the pad and the AmplifiFX100.
I would really not prefer running factory reset also for my iPad, but I don't see if there are anything else anymore I can do. Is there? Does anyone know if iOS9.2.1 is supposed to properly clear the BT registry or bring any other favourable change? I'm running out of ideas here.
