EDIT: this solution isn't a complete solution, there are still issues (read my comment below).
I was having difficulty with this and wasn't sure what the issue was. Whenever you touch a button, the button text would shift to the left side (Android only).
Turns out that when we upgraded to 1.2.2, we were not forced to update Xamarin.Android.Support.v4
from release 19 to release 20.
Go into your package manager, and update Xamarin.Android.Support.v4
and the button shift issue will go away.
@ermau is it worth it to update the Xamarin.Forms
v1.2.3 dependency from Xamarin.Android.Support.v4.19
to Xamarin.Android.Support.v4.20
?
