Firmware update killed Bluetooth music – Spark Amp: Smart Jam, Chords Review

Bought 6 months ago, worked great. Really enjoyed jamming with backing tracks. Installed new firmware update, now no Bluetooth sound. I am able to connect to both spark 40 BLE and spark 40 Audio. Same problem with both iPhone SE and iPad running app software 2.0.0. Have done factory reset and Bluetooth reset multiple times. Installed firmware update 1.4.3.174 twice. Tech Support was unable to Help. Per tech support suggestion I updated my firmware multiple times before the Bluetooth sound starting working again. I don’t understand why it was necessary to install the firmware about 10 times!
