Cover group in paralell

Configuration
1

I have a group of Switchbot Curtains (7 units) and wanted to create a group to have them open and close in paralell but it seems as if the group is all run in sequential and so i tried creating a simple automation with a -choose that opens or close enteties with the paralell mode but it still runs them in seq. mode; any one had this happen or have an idea on how to make this work?

Ultimatly i would prefer to use a group but a automation would be fine if thats the only way. I´m using the Bluetooth integration and the built in Bluetooth adapter in the NUC and not any any esp32 proxies or anything like that.

Any ideas are welcome.

example of the last test using Automation using paralell,

Update, read someone was having responce issues with bluetooth adapters so i installed an ESP32 Proxy and ran the same automation, to my surprise it ran in paralell, once again and it ran in seq. at this point i tested disabling the bluetooth adapter and hassent missed a beat last 10 times.
