I have been creating my own HTML documents as Invoices for 20 years and started using the paypal buttons in them as soon as those were available through paypal. These documents have always displayed the buttons on all devices and have been working correctly for at least 10 years or more, until today. Suddenly the pay now or buy now button does not appear and can not be clicked when opening the HTML document on a cell phone. If the document is opened on a computer it displays and works correctly. When looking at the code I can not determine why it would suddenly stop working correctly.
