If you have a newer IOS (iPhone) and have not received message previously:
* Settings App
* Block Cookies
Do you have this setting set to the default of “Allow from Websites I Visit”? If not, and it is set to “Always Block” then the login will not work for ItsPayd or any other website. Basically a cookie is required to keep track of whether the user has successfully entered their access code (which we automatically pre-fill for them).
Please configure cookie settings to the default of “Allow from Websites I Visit” and see if that works. If already set there and still having same problems, then most likely it’s an iOS problem.
