When downloading mobile map packages created from WebMaps in ArcGIS Online > Settings > Manage Offline Areas, include the layers of the map package and not just the basemap.
We want to be able to create detail rich offline maps for use in Survey123, but limit file sizes. Our data also changes regularly, so utilising a webmap with scheduled repackaging makes sense. But only the basemap shows up in Survey123 - no map layers.
The only way it seems to get imagery and map layers at present is to create a .tpk in ArcGIS Pro - slow and manual. No thanks!
