FYI:
I wonder if you with Snowmass 3.0.0, and weren’t able to update your Bridge II via the DS display are experiencing this: https://forum.psaudio.com/t/snowmass-version-v2-is-ready/8036.
Here it is reported that Snowmass 3.0.0 doesn’t have the functionality to update Bridge II.
I’m in this situation, so I will have to install Snowmass 3.06 before I try to update my BII, it seems.
