Description

Xamarin Forms 5.0.0.2012 on iOS (14.04) only displays the last two digits of the year where previously displayed all four.

Steps to Reproduce

1. Implement a DatePicker in an iOS Forms app and set range from 1/1/1600 to 12/31/2399.
2. Run with iOS simulator
3. Picker will display the date as M/d/yy i.e. 3/2/21
4. Select another date and the picker still only displays the year as the last two digits.

Expected Behavior

3/1/2021

Actual Behavior

3/1/21
