The issue is still there in 3.34, reported upstream now

https://gitlab.gnome.org/GNOME/gnome-bluetooth/issues/52

Note that 18.04 is still missing the fix for bug 1887910, which sounds related.

Hi @Sebastien,
May I know what gnome-bluetooth version is this fix available in? I ran updates on my system earlier and I'm still getting this issue.
Please see information below:

OS: Ubuntu 20.04
Gnome-control-center: 3.36.5
Gnome-shell: 3.36.4
Gnome bluetooth: 3.34.3

Thanks.

This bug was fixed in the package gnome-bluetooth - 3.34.5-1
