So the test button is and stays greyed out, regardless of the value I give it

I noticed this behaviour earlier when changing 1S0 BCMs (1S0 937 087x / 090x) but I was too focused to document it..
I managed to do it with another tool though. Fun fact, the VW O-tool also didnt succeed...
I dont do a BCM change every week but it feels like this is new in the 25.x versions of VCDS.

I dont do a BCM change every week but it feels like this is new in the 25.x versions of VCDS.
Let me know if you want to test some previous versions.
