Just here to say my H9 Control app for Windows 10 has been unusable for the past month as well. I must turn on/off H9 pedals and plug/unplug BT dongle as well as switch on/off bluetooth on my PC to maybe just 1 of the 2 pedals working. All in all, it works after about 30 minutes of trying different things. I even did try unistalling the app and re-installing.
It’s sad I just bought these, and all I got is a big black scroll wheel to take me through presets…..
I hope an update comes soon 🙂
