I recently got a Line 6 AMPLIFi 150 with an FBV Shortboard MK2 and I have been having some issues with the Bluetooth and syncing. I have the app downloaded on my iOS device but the moment I hook up the amp and the board, and sync the phone to the amp, the syncing screen stays up forever and it eventually times out. The amplifier and board themselves work fine, but they do not respond to configuration from the iOS device, nor the Spider V Gearbox program on the computer right next to it. My daughter factory reset both the box and the amp for me, but that doesn't seem to be changing anything. If anyone has a solution, I would love to hear it, because I am lost.
