I would like to know up front what errors have already been identified, so I don't spend time looking for a solution myself.
Here is an example of a possible 'bug'.
Upload a 10.1 sp 1 file geodatabase (zipped) & then generate Feature Service so that staff may setup a map to work offline later.
In editing mode, there are three options in the Feature Service Properties for enabled Editing...
Editors can add, update, and delete features.
ONLY option #1 works. IF I choose option #2 or #3 staff can't download the map containing the Feature Service, because it won't show for them as available. We are using IE 11, Both Android & iOS smartphones, iPad.
