I'm new to ArchiCAD and I'm following this video, with same dwg for external reference downloaded from here, but when I attach it, the Xref's drawing does not appear at all. I tried by drawing another dwg myself with an Educational AUTOCAD 2020 and attach it too, but it doesn't work either. It seems I can't see any Xref I try to work with my ArchiCAD.
Only difference from links is that I'm using an ArchiCAD 23 BRA.
