Thank you so much

I am a little relieved that you are the same as me.
I received the following reply from the support team.
"This issue occurs because the UAC you are connected to only supports 32-bit, which is why it cannot be selected."
This is a bit odd since the D30 Pro's USB is supposed to 16-32 bit, but this seems to be normal.
Btw when I connect the Bluetooth adapter to the Ultra's USB it shows this. There seems to be no problem here.
