Last night around 7pm EST, a bug was added into the system that has caused some sporadic behavior. 
This bug was identified and resolved at 4:45PM EST today.

As a result, you may have experienced getting logged out unexpectedly and data not saving and syncing properly to other devices.

I apologize for the inconvenience and will continue to do my absolute best to make Inventory Now a simple, robust and stable platform for your needs.
