One of our field crews is experiencing frequent crashing of the collector app on the iPad and also lots of lagging. The iPad is iOS 8.3 and is up to date and the service has about 2500 points with 290 attachments. There's about 50gb of space available on the iPad so I don't think it's a storage space issue and it works fine in other iPads and in a connected environment.
We're using ArcMap 10.2.2, ArcGIS server 10.2.2 and SQL Express 2008 R2 to store our enterprise geodatabases.
If anyone has any tips or solutions it would be greatly appreciated!
