ArcGIS Pro 2.9.1
A point feature class (Manhole) was published with a related table (Manhole Inspection) from ArcGIS Pro to AGOL and was used for data collection in Field Maps. Therefore the field users used the related table link in field maps to perform their inspections (including pictures).
Now, after collection and bring the feature service back to ArcGIS Pro, I am unable to access these photo attachments via Spatial Map Series Layout > Insert Picture > Format Picture > Dynamic Picture > [Attachments] filter. The other data fields are perfectly accessible. Also, this workflow works perfectly fine when the photos are collected directly on the feature service.
I have tried many combinations of joining the inspection table to the point feature service, downloading the service to a FGDB, creating a spatial map layout series on those layers, joining the FGDB the ATTACH table, to both the current service and also the downloaded point layer.
Any suggestions would be greatly appreciated!
