I have a survey in Survey 123 where I have added the feature layer into a web map. This operation was working fine up until yesterday when I tried to download an area in Collector or create a offline map area in ArcGIS Online; this operation fails in both applications. I know it has something to do with the Survey 123 feature layer, by process of elimination the offline services work when the Survey 123 created feature layer was not in the web map. Also, all the layers are set up for offline ("sync") use. I can't figure out why it suddenly stopped working, I even tried recreating the survey but no luck. If you have any suggestions I would greatly appreciate it!
