I have georeferenced PDF files (exported from ArcMAP) that contain drawings made in Adobe Acrobat using the drawing tool on an Android device. When I add the PDF to ArcGIS Pro (using ArcGIS Pro version 3.4.5 right now), it is positioned correctly in terms of location and orientation, but the drawings are not visible. Hower, using a standard PDF viewer or QGIS 3, the drawings appear fine.
Any suggestions how I can get ArcGIS Pro to show the drawings in the PDF file?
