hello. I am kind of new to ArcGIS online and I just publishes a feature hosted map service after I have fixed my data with subtypes and subtypes-domains. after publishing to agol I discovered that all my domains are not working. please advise. I need this for collector. and I had intentionally created the domains based on subtypes in order to restrict the data entry based on the subtype.
Please describe your workflow a bit more. #AGOL supports both domains and subtypes in Collector.

You need to use a unique value renderer on the subtype field.
