Amplifi 75 (current firmware); iPhone 8 ios 11.2.1; Amplifi 2.6.02: I had recently thought the performance of the BT connection and iphone app syncing with amplifi 75 had improved, until randomly now, I cannot connect to amp. BT connection is fine but App wonâ€™t sync with Amp. Iâ€™ve tried all typical troubleshooting steps. Finally reconnected after rebooting phone, amp, stopping/starting BT, â€œforgettingâ€ BT connection/reconnecting. How long will it work though? Iâ€™ve been through this countless times in last two years. I still like the amp when itâ€™s working but am really tired of the challenges. Canâ€™t tell you how often I lose inspiration by the time I get the rig up and synced. As a bonus now, all of the sounds Ive saved are all duplicated 8-10 times. A mess!
