I’m having trouble getting a web map to load consistently in Field Maps on my iPhone. I work for a large organization that uses an ArcGIS Enterprise Portal. I am the owner of the web map and it has been configured for offline use. I frequently get the following error “unable to open - user cancelled error.” After a few tries the map will usually load. It does have some large datasets in it, maybe that’s part of the issue but I’m not sure. I don't have any issues downloading offline areas. Interestingly, I’m seeing a lot of unregister lines in the log for layers which are not in the map I am trying to open (or in any of the maps that I use).
I believe the relevant entry in the log is regarding network connection lost and error domain code =-1005. I have issues on Wi-Fi and on cellular data so I do not believe it is actually a lost network connection. Unfortunately, I can't post the troubleshooting log here due to security. Our GIS team suggests that it might be due to the size of the layers in the map. I'm wondering if anyone has different ideas.
