Problems with PayPal checkout
If the PayPal checkout does not work after logging into your Paypal Account. Please clear the cache on your mobile Google Chrome or Safari Browsers and/or log into your Paypal Account on your desktop to turn off two factor authentication.
Once the above are done, you can try paying via your PayPal account again.
If that still does not work, please free up the storage space on your mobile phone and try again.
