My app was working fine until I've updated to Forms 1.5.1.6471. I get 30+ errors like this:
/Users/.../Android/Resources/Resource.designer.cs(124,124): Error CS0117: Myapp.Android.Resource.Attribute' does not contain a definition forcardBackgroundColor' (CS0117) (Myapp.Android)
Some other posts suggest to change target to API 21 but it does not solve the issue, is anyone having the same error?
