Platform: Android 4.4.2
Device: Nexus 7 (2012 model)
Doit.im version: 4.0.7

Observed behavior:
Creating a new task via the Android share mechanism results in a task in the inbox that a) doesn't sync and b) cannot be manually deleted.

I've tried sharing from different Android apps (Feedly, Chrome) and the behavior is the same. I've also replicated this on my Android phone (Galaxy S4).

The only way I've found to remove the tasks is to log out of the app & remove local data.
