Problem with ArcGIS Pro failing to georeference when exporting to PDF

[HollandYoungman]

I'm exporting maps from ArcGIS Pro as pdfs for use in the Avenza app. Recently, the maps are showing up as "not referenced" in that app - even though I'm specifying that the georeferencing be maintained when exported from Pro. I can make the same map in ArcMap, export it as a pdf and open it up in Avenza as a referenced map. Has anyone else been having this issue? Or care to share some advice? Thanks!

I've tried exporting to PDF from ArcGIS Pro 3.2 using the suggestions above (uncheck Compress vector graphics, Adaptive image compression, Export georeference information) - but this still imports into Avenza on my iPhone XS with most currently iOS (17.1.2 just updated this morning!) with the red Map Not Referenced. There is no problem with PDFs exported from ArcMap - but this is not a sustainable method since we are migrating all our MXD projects to PRO and they are not backwards compatible to ArcMap at that point.

Note: I reached out to Avenza tech support (using the Avenza Plus personal subscription), but have received no help (just an annoying sales pitch to upgrade to Pro).
