Has anyone else been able to figure out how to make the Bluetooth connection stable? The Firmware update is current (3.xx). I traced a few old internet discussions from the early days of Version 1.xx. The problem existed then. I'm using a Galaxy Note 20. That model is notorious for maintaining connections with devices. I've also heard of similar dropouts from iPhone users. I use my Mustang Mini with zero issues. It's hard to understand why the full size amp can't handle what the USB drive-sized headphone amp can.
