Hi there!
We use Workforce with ArcGIS Enterprise, and today one of our mobile workers came across this issue when trying to open the map (screenshot attached). It was their first time signing in and trying to open the map.
Unable to Open: Assignment types table is missing from map
We've previously had this issue and fixed it by reinstalling Workforce. However they tried this a few times and this doesn't seem to fix it.
We do have sync enabled on the layer, and it all other users can open the map.
Any help would be greatly appreciated 🙂
