Meteorjs payflow intergration working on website but not on ios app

Im trying to integrate payflow into my application. Its working fine on website. But in ios app Im getting the following error :
ERROR Internal navigation rejected - not set for url=‘https://pilot-payflowlink.paypal.com/’.
My code:

<form method="POST" action="https://pilot-payflowlink.paypal.com">
<input type="hidden" name="LOGIN" value="my vendor ID"/>
<input type="hidden" name="PARTNER" value="my partner"/>
<input type="hidden" name="DESCRIPTION" value="Order description here"/>
<input type="hidden" name="AMOUNT" value="amt"/>
<input type="hidden" name="TYPE" value="S"/>
<input type="submit" className="btn" value="Pay Now"/>
</form>

I have done all the required setup on manager.paypal.com website. Any help would be greatly appreciated.

Thank you for your reply. But does it support ios also?

It’s a core part of Cordova. It controls your application’s access to outside resources.

Thank you so much. I will try this

I tried but its redirecting to a blank page.
