ArcGIS Pro 3.3.2 stopped displaying north arrows with correct magnetic angles

ArcGIS Pro 3.3.2 has stopped displaying north arrows with correct magnetic angles.

A work colleague produced a map and created a custom compass rose with True North, Magnetic North and Grid North all present. The arrows all aligned to 0 degrees instead of the correct values.

I checked an APRX from a previous project from last year which had a correctly functioning compass rose and it is also failing to draw correctly now.

Is this a new bug in the Pro application, or is there something else happening that could cause this?

incorrect alignment (in APRX in ArcGIS Pro today)

No elaboration or workaround

BUG-000172739 for ArcGIS Pro

but it is fresh off the press and reported for 3.4 but maybe it existed previously so you might want to check for details with tech support

Thank you Dan, saves me pulling the rest of my hair out for now.

Is there any chance of a patch to fix this so we don't have to wait (and upgrade) for 3.5 to have a fix?

Thank you for reporting this! This is actually not BUG-000172739 for ArcGIS Pro which is a 3.4 bug. What happened here is magnetic north is calculated using NOAA coefficients. There are new coefficients for 2025-2030. We are actively working on the best way to get these out so magnetic north works properly again.

Hi Aubry,

Thanks for updating this for us. Looking forward to getting this working again. We have a number of projects that require this functionality, 1 of which is a set of map series with 100s of pages where we really don't want to have to set each compass rose manually.

many thanks, Pete
