Map Download Fail/cannot file msd AGS + Portal + ArcGIS Data Store + Collector
On premise we have the full stack of ArcGIS at 10.3.1: AGS, Portal, ArcGIS Data Store. The ArcGIS Data Store is an out-of-the-box configuration. The PostgreSQL geodatabase backend is used. I had my DevOps install and configure the ArcGIS Data Store for my hosted services (feature layers and Survey123).
Following the instructions for publishing a hosted feature service here: https://blogs.esri.com/esri/arcgis/2015/02/18/related-tables-exploring-new-ways-to-use-collector-for... (in fact, using the sample data from HydrantInspections!)
I have enabled the feature service for offline use. GlobalID are there, etc. offline is enable in Portal, etc.
In Collector I attempt to download the map and get the error below.

So... Can anybody give me a hand with this?
Another error I am seeing when trying to download the map is:
