Hello @komal_garg2
Found this in one of paypal forum
The problem is with Safari not rendering the iframe correctly, PayPal has nothing to do with it.
The PayPal Pro Hosted checkout within the iframe is not meant to be mobile, in fact in order to make it work you should redirect the buyer to PayPal.
The issue here is with EKM and any other third-party carts out there that do not manage the flow correctly. There should be an exception so if the browser is a mobile one the buyer should be redirected to PayPal instead of attempting to load the iframe.
