[iOS] Billing Postcode entry not working at Device

[xleon]

Steps to reproduce:

• use a release version on the iPhone (as it works fine in debug mode and simulator)
• create and show a pre-auth page
• enter CVV2
• try to enter billing postcode

Result:

• The soft keyboard appears
• I can´t write anything in the billing postcode
• When I navigate back, the soft keyboard remains on screen
• When I repeat the process, an unhandled exception makes the app crash

Expected result:

• I should be able to enter billing postcode and send / authorise pre-auth
• The keyboard should work fine and disappear when clicking "next" or when navigating back to the previous page
• The app should not crash

We noticed 2 different crashes at our raygun reports

Hey @xleon, thanks for reporting this. I assume you are using the latest version of the SDK and Visual Studio / Xamarin tooling. Can you share which iOS version and which device this is happening on?

Xamarin.Forms: 4.1.0.618606
iOS 12.4.1
Device: iPhone 6s

Here´s the xamarin tooling (I´ve just updated to the last preview, but the problem happened before that too.
