Example of iOS Pickers not updating when unfocused.
I've got a set of Pickers that are all visible simultaneously. On iOS, when using a Picker, if you select a value but don't click "Done" before tapping a different Picker, the unfocused Picker will not update the selected value. If you switch back to the first Picker, though, the selected value is still selected. (On Android, the Picker takes full focus and the user cannot switch between them without an implicit cancel.)
Adam, thanks for submitting this issue. Could you kindly attach the small reproduction you used to demonstrate the issue in the video?
Looks like I owe you an apology for the false alarm.
I knew the originally affected project was running an older version of Xamarin.Forms, but I thought I had the latest version of Xamarin.Forms in my repro project where I created that GIF. Turns out, I had only updated the core project's Xamarin.Forms package and left iOS out-of-date on v188.8.131.5223 (from the new project template).
After I also updated the iOS platform Xamarin.Forms package to v184.108.40.20676, the issue went away.
