SfExpander crashes on Android

[George]

It works on UWP  but crashes on Android with this exception after opening and closing it then trying to open it (or any other expander) again:

**Java.Lang.IllegalStateException:** 'Unable to create layer for ExpanderContent, size 1088x0 max size 16384 color type 4 has context 1'

There are multiple expanders on the page but all of them seem to cause the crash. The layout is something like this:

 

EDIT: the forum ate my XAML, dunno how to format it properly. Here is a pastebin instead: https://pastebin.com/1tvN1fW9

Hi George, 

  

We have checked the reported issue in our source, the issue occurs in Xamarin Forms Native control. It had been reported to the concern team already. But they have informed that the provided information is insufficient. So, we have reported with the issue replicating sample in the comment section. So, you can track the status of this report through the following link. MeanWhile, you can overcome the reported issue by using Grid instead of StackLayout in Expander Content.

Once, Xamarin team updated with workable solution, we will update you the further status of this issue fix if included in our future releases.  

  

Kindly let us know in case of any queries related to this.
