Is anything being done about this? It's more than a year since it was logged (admittedly the person who logged it missed off the detail, which I have added below).
On UWP, WinRT 8.1 and WinPhone 8.1 RT, System.Globalization.CultureInfo.OptionalCalendars provides me with a collection of calendars, so that I can make use of not just a Gregorian calendar but also Hijri, Hebrew etc. However, on Android and iOS, I only ever see one calendar in the collection. Can you please advise whether Xamarin.Forms populates OptionalCalendars correctly on Android and iOS, or whether there is something I need to do on Android and iOS devices for this population of more than one entry to happen?
