[Sekharonline4u]

Hello Team, I was trying to use JudoPay payment integration for one my client's application to do that I was trying to create a sample Application using Xamarin.Forms 4.7 and Xamarin.JudoPay (5.3.1) once I have provided the Credit Card Details , Expiry Date and CVV Number provided at the Tools options and click on the Pay button "Processing Payment" statement is displayed and the screen is blurred and for more than 1 hour it was just rotating. Am getting the same issue in both Android Device and iOS Simulator also.

Kindly let me know the solution
