Offline

[jcarbaugh]

We need to think more about how offline is going to work in the app. We have a weird mix of stuff that will work because it's cached and then suddenly fail when you try to go to a screen with uncached data.

Maps work (disappear, but not crash the app) if you are online and then lose connection, but crashes if the app NEVER had network connectivity (state restoration into a cached view such as Followed and then into a legislator detail page). I believe this is because the app never receives network state change information (network state never changed).

Not sure what to do. Thoughts?
