iphone demanding passcode for fingerprint id
Randomly, my phone demands my passcode for not being used within 48 hours. However, I have used it frequently within the prior 48 hours. The last time I had the problem, I contacted support who suggested I wipe my phone and re-install/restore backup. I did so and the same problem just happened just over a week after I re-installed and restored. This seems like a bug, not a feature. Does anyone have any idea how to prevent this? I would prefer NOT to remove my fingerprint lock.
