It may happen that while selecting PayPal as a payment option, you’ll be presented with the following screen. 

Would that ever happen, navigate to the top right corner of the screen and click on the icon marked in red circle in order to display blocked pop-up content. Set the content to ‘always allow pop-ups’ from Pulseway and click on Done to approve the change.

Once the pop-ups from Pulseway are successfully set to be allowed on the browser, the usual PayPal log in screen will be displayed and you’ll be allowed to continue with your shopping in the usual manner.
