I have an iPhone 5. I've been a 1Password user for about 3 months now. I have the app configured to use a PIN to unlock my vault. Under Settings | Security, I have "Lock on Exit" enabled, Auto-Lock set to "1 Minute", and "Pin Code" enabled. Up until a few weeks ago, these settings were working as expected. The app would always ask me for my PIN to unlock my vault. It would only ask me for my Master Password if I messed up and entered the PIN incorrectly (or if I did a full restart on my phone). Some time over the last 2 or 3 weeks, it stopped working correctly. It will ask for my PIN most times I open the app, but if I haven't opened it for say a day, it will again ask me for my Master Password instead of my PIN, even though the phone hasn't been restarted. This happens at least once a day. I'm guessing that something in one of the recent software updates has caused a problem with the way this works. Any help to get it back to working the way it's supposed to would be greatly appreciated.
