Can't Complete Sales. Used PP for years with no issues and then since the start of the year finding paying for things a pain. Started with eBay where you would chose PayPal to purchase something and the "processing" screen would just stay on all the time without completing the sale. This is happening on other apps now. Seems your new security authentication is the problem. And don't bother sending me the "problem must be your end" message I see elsewhere. I have started using other methods.
