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?
