Description

When the app launches the SetCulture method is called, set the apps culture to what the user has saved.

This works completely fine on Android, but on iOS StringFormat in the xaml doesn't use the set culture, and stays as english -

I've also tried doing the StringFormat in the model, and it also doesn't work -

Even setting the culture manually doesn't work -

It all worked fine in Xamarin.Forms, and it is a valid .NET Culture -

Did you find any workaround?

No, unless this is fixed, the only way I can see to work around it is to add a property to the API and perform the translation there.
