First off, this stems from an issue where appending live, hosted layers in ArcGIS pro would not transfer attachments properly from the appending to the append layer. I had about 330 photos to attach to the newly appended points, and managed to get the photos attached to the appropriate points in the end. I can see on AGOL that the attachments are there; I can view them and download them.
In a map series I have of this live layer, there is a dynamic image box that is supposed to automatically display the attached images. However, it will not display any images that were attached using the "add attachments" tool; I have tried turning off filters for the picture name, re-adding the data, refreshing the map series, among other basic steps, and nothing is working.
So, in summary:
How can I make the attachments added from ArcGIS Pro, which are visible on AGOL register with my ArcGIS Pro map series? It is too many photos to manually redownload them and reupload them.
Thanks!
I had the same issue and realized that it was my version of ArcPRO (3.1). No issues with ArcPRO 3.2.
