TLDR; this app is non-functional.
My FLY TWS headphones connect to both my phone and tablet’s bluetooth just fine, yet this app *insists* it cannot find them. I follow all instructions, try different configurations of headphones being in and out of my ears with the open case, “forgetting” and reconnecting to them, bluetooth and phone turned off and on again, no music in the background as instructed (or any open apps of any sort)… nothing.
What a letdown. The customization was a cool little selling point for me, and the first thing I wanted to play with. Instead, it turned my first experience into instant frustration. Blurgh
