Hello ,
Thank you for posting in the community the issue with the North Arrow on the plan (orthogonal top) view. We have documented this bug and will be addressing it in a future release. Thank you for your patience and understanding.
I also checked the viewport north arrow and shadow location based on the scene location and comparing it to the a sun rise and sun set calculation data. It seems to be correct as the North is not always set at noon for many places.
Kind regards,
Vincent B.
