How do I set a 4-digit passcode in iOS 10?
I have an iPhone 6s with iOS10 and my phone started prompting me with a "Passcode Requirement". I had a 4-digit passcode, but it will now only let me enter a 6-digit passcode. I want to go back to the 4-digit passcode (for a variety of reasons), but when I go to "Passcode Options" under "Set Passcode" like it suggests on the Help page, the only option is for a "Custom Alphanumeric Code" (which also has to be 6-digits). How do I go back to the 4-digit passcode?
iPhone 6s, iOS 10.2.1
