ArcGIS Online recently changed the user types from 2 options to 5 options. We purchased a few viewer accounts and editor accounts(Level 1&2). We did this so that people could use the Explorer app out in the field without changing any features. Now we can't access the app from those logins. Is there a grandfather program because we prepaid for these accounts and now we can't use them with the apps. Kinda defeats the purpose of even having them now. Do I really need to upgrade to Field Worker accounts which I don't really want because these people don't need to edit or change things out in the field.
