hi dont know if this is the right place to post this but here goes. i am having problems with ebay and paypal. when i buy from ebay and it goes through to paypal a window comes up saying add security key to end of password. i have linked mobile phone to paypal but can not find a way to get this to work. paypal is fine on laptop but not ipad. i have downloaded the paypal app also. Any help would be great. Thanks.
