Well, it already took much longer than I expected 😅
That second person told me on Reddit he was just randomly touching and holding the buds on the home screen of the app, and all of a sudden, it appeared. Another person has mentioned that in the discord (no idea which) they found out it gets activated if you install an older version of the app.
But yea I’ve also tried a lot, from entering stuff as device name, to clicking, holding, swiping stuff, nothing happened. Kinda feel like an idiot 😃
