Hi, can you see if here blueman-project/blueman is more suitable for this bug?

Restarting Pulseaudio worked for me. Try this:
pulseaudio --kill
pulseaudio -vvv --start

I don't know what the policy with respect to upstream bugs, but I think this bug should be reopened.
Since LinuxMint integrates blueman this is also an issue in Linux Mint.

For my two Bluetooth headsets, using bluetuith was a workaround to establish a stable connection on LM 21.2 CE.
