We have a custom location for PC3 & PMP plot config files, which have the standard margins etc. tweaked so PDF files look the same on the "page" as our printed output.
All has been well till LT 2020 was rolled out. Randomly, we find PDF's have the correct page size (A1 for instance), but the actual view is the bottom left hand corner zoomed in to about A4 size.

I've reported this issue to Autodesk Support, but I think they were having an off day, and I didn't get it resolved with them.

Has anyone else had a problem with this?
