We have created a SfButton in XAML as below. When we try to access the AutomationId on UWP we can't see it. It is, however, visible on Android. Setting the AutomationId on other controls (e.g. SfBorder) works correctly on Android and UWP.
<sf:SfButton
Grid.Row="0"
Grid.Column="1"
Text="{Binding QuickAmountButton2Text}"
Command="{Binding CreatePaymentCommand}"
IsEnabled="{Binding PaymentButtonsEnabled}"
AutomationId="QuickAmountButton2"
AutomationProperties.IsInAccessibleTree="True"/>
