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.Regards,Sangeetha Raju.
