I'm testing the same webmap in Field Maps and Collector. In this webmap, I have a mapservice that includes a layer that gathers all inspection activities on a feature so that we can draw a colored shape on top of assets that have recently been inspected. This map service draws on top of the feature service that contains the assets to let field staff know that their inspection is complete and to move on.
When I perform an inspection the colored shape draws almost instantaneously in Collector. In Field Maps, it will not display. I've had to kill the app and reload it for this shape to draw/the layer to trigger looking for an update to the data. Turning on and off the layer doesn't trigger a refresh neither does zooming in and out.
Is Field Maps caching the data differently than Collector? We've even setup this test to directly tie to the REST service URL coming from our ArcGIS Server so the AGOL CDN doesn't come into play.
