Is anyone else experiencing serious performance issues with the Amplifi app? It used to work perfectly, but I started my Amplifi TT up for the first time in a few weeks, and now I cannot get the app working at all. Most of the time, mine crashes while syncing after opening. Sometimes, it completes the sync, connects, then crashes. I have everything updated, reinstalled the app, applied firmware updates, restarted everything, and I'm experiencing the same issues on my iPhone 6s and 4 week old iPad Air 2. Line 6 support have advised that my Amplifi TT could be the fault, but why would an external device connected by bluetooth cause an app to crash completely? Surely crashes indicate a stability issue with the app. Line 6 have also suggested I reinstall the latest iOS update. Before I go through the upheaval of performing a restore on my iPhone, has anyone tried this and fixed the issue? I'm sceptical it would work. I am loath to contact Apple, as they don't provide support for third-party apps; a full restore is probably just what they suggest in the absence of being able to advise on another company's software. All reviews on the app store are from people experiencing this issue, but Line 6 advise that there is currently no scheduled app update.
