I have an ArcGIS.com map that uses a public map service from our ArcGIS Server. A key field is stored as a subtype. The subtype renders in the pop-ups on ArcGIS.com and iPad, however it does NOT render in the pop-ups on the iPhone.
What are the versions of the app you are using? and.. Can you share publicly this map for a temporary time? I would like a second to check it out and if it is an issue I will check to see if this issue has been fixed for the next release. Thanks Russ
Apologies! Although I thought I had updated, when looking to answer your question about which version, I noticed there was another upgrade (2.0.1) and after I upgraded, the subtypes rendered in the pop-up. Thanks.
