An arrow is displayed inside the appointment in cases when:

- when editing the appointment star end date and navigating to another week and then returning back to the week with the modified appointment

- adding new appointments to the week

In the RadCalendar, if we set the DisplayDate to future date (For example, current date is 04-03-2024 and the display date as 08-April-2024), application gets crashed in iOS platform. This issue occurs only in iOS 17 and above versions.

Exception

NSInternalInconsistencyException Reason: UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={0, 0}

When changing the view mode from Day to MultiDay or opposite, and having an AppointmentTemplateSelector, exception is thrown on iOS. 

workaround: 

Return the default template when platform is iOS.

if(Device.RuntimePlatform == Device.iOS)

            {

                return default;

            }

When adding a RadCalendar with Day ViewMode in a TabView and switching tabs, null ref exception is thrown. 

Workaround: Set TabView.IsContentPreserved to True 

When changing the device orientation to a landscape mode, the all-day timeline cell does not resize as expected. The all day text moves the the date cell.

white/dark space is shown on the top of the agenda view. This space hovers some of the vents and dates from the agenda. 
You need to scroll through the agenda and the white/dark space disappears. 

Additional add appointment button is displayed when the device orientation is a landscape and the calendar view mode is Year. When switching from Year to day/multiday the issue happens in these views too.

The issue can be reproduced in the Telerik Xamarin Sample App/Calendar/Scheduling example 

Go to Year view, rotate the device in landscape mode, second + button is displayed inside the calendar title (year name)

Then rotate the device in portrait mode and go to day/multiday view,  
Rotate in landscape mode -> issue occurs. 

appointments show wrong time in different time zones due to daylight time changes.

The issue can be reproduced in scenarios:

- For US time zone 14th of march: If I click an empty slot, I have a popup that tells the time that is clicked. I click on the 9 AM slot and it says I'm clicking on "10:00". This only happens on 3/14/2021

- For European countries time zone: on 28th or march 2021 when is the daylight saving time

On Android,  when the user selects a date on CalendarViewMode.Month mode, the DisplayDateChanged event is fired twice and the displayed date in CalendarViewMode.Day is incorrect. 

Sometimes the display date is 4-6 months ahead/behind or just with one month.
