I just upgraded to MATE 21.04 on my Raspberry Pi 400, and I am having trouble with pairing my JBL Charge 3 Bluetooth speaker.
I've tried to connect to it multiple times with blueman, but it keeps saying Error: Resource temporarily unavailable. when I try to connect to it.
I can connect to it just fine with Raspberry Pi OS, but I can't do it with this for some reason...
