I use 2 tablets with iFly for maps when I go flying.  Both of them had some issue trying to authenticate with the server when I went flying this morning.  I have over 400 days remaining in my subscription so I'm sure this was some sort of issue that will be resolved.  I had no way to get to maps, no failback that I could figure out.  I understand the need for security and not giving away free service to expired accounts, but this was not acceptable.  Thoughts?
 
Figured out the issue, I had changed the password on the website and not yet in the app on the 2 tablets.  The problem remains that when I was out at the airport with no connectivity to the internet, with valid subscription and up to date maps, I was locked out of being able to use this app.  Seems like I should have been able to access the maps already downloaded.  Either that or the app should be able to remember I had a valid account, or some sort of grace period so you don't get stuck like this.
