Since upgrading from Ubuntu 20.10, my internal bluetooth card as well as an external usb dongle will not work. Bluetooth starts as off, and cannot be turned on. If I use systemctl to turn it on, it is on but doesn't find any devices through bluez. Blueman finds devices but cannot connect to them. The hardware on this machine has remained identical; the only difference is the new version of Ubuntu. Hence the problem has to be software.

We haven't had any bug reports like this that weren't hardware-specific. Maybe to avoid confusion here we should choose just one Bluetooth chip. Either the USB dongle (Broadcom Corp. BCM20702A0) or the internal chip (Intel AX210/AX211/AX411).
