Steps to reproduce
Make sure an inbox destination is set both in web app and android app - app works correctly when online.
Quit previously running Dynalist app from android running apps overview screen.
Set device network offline (flight mode)
Open Dynalist app.
Look at settings
Under "Your inbox" should show last Inbox setting.
"Your inbox destination is not set"
Dynalist 1.1.22 on Android 5.1
Looks like none of the settings are persisted, so when the app starts offline they all revert to their defaults.
Being unable reliably to share text selections to to Dynalist inbox while offline is a showstopper for note-taking -- if you try to do this and the inbox is not set then the selection is lost. It only works when the app was already running while online.
