Is this the problem, or am I setting up something wrong?
Check your Settings to be sure that you only have a Home setup and that the location is set to Home and you have chosen NOT to auto-change the location. This is what was referred to in the last post, which was spot on. Now, the app shouldn't attempt to switch if the address is blank, but just to be sure turn off that auto-switch.
What tablet is this? I can see if the error was serious enough to be sent as a crash report (though this would not get sent if it is just a network error or something). Model or other identifying information would be the most helpful as it will only have very generic device info in a crash report.
