We are using portal and created a map for Collector. The issue I think that is causing us problems is that the web map is made up of map services that are not configured for off line work. We have 3-4 different sources (we don't 'own' those services) and our own map service going into this web map, so I am guessing the download errors we get from collector are because only our Map Service is offline ready?
anyone have any insight? I am still trying to read through the documentation, but thought I might be on the right track to ask.
The server must be 10.2.2 and all content must be downloadable. If you are using map services you must have export tiles enabled and feature services need to have sync enabled. The app will not skip over layers that cannot be downloaded.
Our site is 10.2.2 that hosts Portal, but as I suspected the other services we have tapped into to supplement our site are the issue. We have no control over them, and they vary in ArcGIS for Server level.
