Moving Switchbot Tilt cover group simultaneously

I have a cover group, created using default helpers, consisting of three SwitchBot Blind Tilt devices (connected via Raspberry Pi 4b+ built-in Bluetooth).

The group used to move simultaneously, but after some Bluetooth issues with HAOS 10 were fixed, they now only move one at a time, resulting in it taking almost a minute to open and the “wow” factor really disappearing.

Is there something wrong with my configuration causing curtain actions to not run in parallel, or anything I can do to restore that functionality?

I am experiencing the same problem with the same setup (3 Switch Bot Blind Tilts in a group @ Raspi4) I just got them a few days ago and was a bit disappointed that they only move one at a time. At least good to hear that’s not the expected behavior.
