I created a feature on ArcGIS online, added it to a map and configured it with Field Maps Form Builder. My map is simple and the settings are configured for offline use. My feature is also configured for offline use. In the Field Maps app I have the option to download offline areas, but the wheel gets stuck at about 1/4 of the way then a few minutes later says that the download failed. I'm using a Pixel 5. Others that need to use this map are having the same issue with their iphones (not sure which iphone). It is associated with the feature not the basemap or other layers.
Another note: I tried both large and very small offline areas and it does not matter if the download size is small or large.
Are there any known issues with downloading offline areas with features created online and configured in form builder? Form builder seems pretty convenient if it can work offline.
I just created a new feature in Pro, added that to the map, and took the old one off the map. This works as it should but I still want to know what went wrong.
