Speckle `commits` returning 0

Speckle Help Help (Legacy V2)

Hi,
After the change to V3, our projects stopped working. We tried to move to a workspace, and encountered the same error still.
Basically using the old V2 unity connector:

  _receiver.Commit.RefreshOptions();
  IReadOnlyList<Commit> commitList = _receiver.Commit.Options;
  Debug.Log(commitList.Count); // 0

I’d like to add that Stream and Branches do return correctly. I’m using the old terminology here to avoid confusion as we are still on v2.
Please advise on how to proceed as V2 should still be supported from what I understand (we also need the revit properties etc not just the model)

Thanks!
