[iOS][MacCatalyst] ScrollView's size is not being recalculated, when the size of content changes
Description
I have ScrollView with MaxHeightRequest set to some value and VerticalOptions set to Start. ScrollView has VerticalStackLayout, which has few expanders. When user expands expanders the size of scrollview remains as initial showing only headers of expanders.
On Android this works well

Did you find any workaround?
yes. You need to extend scroll view, override OnPropertyChanged event and check ContentSizeProperty. then just call InvalidateMeasure();
