Cannot log in into EA reward page

ADVICE FROM CITYKITTYSF WHICH WORKED FOR ME!!!

That happened to me. If you go to the page to claim your freebie, scroll all the way to the bottom. In small print you will find “your privacy choices”. Hit it and turn on functional cookies. You then should be able to collect the $15.

Using Windows 10 this is what shows when I pressed View Site Information

When I try that it says:

"Enable functional cookies to use google, facebook or apple login. Without them, only email login will be available."

So my question is, where do I enable cookies on my iphone or laptop?

Superion777​ - next to the URL in your browser, there's an icon for "View Site Information". Click that, choose Cookies and Site Data, then Manage on-device site data. In the pop-up there are buttons to Delete Saved Data, which will clear your current cookies.

Here's another way to get your free gift. Rather than trying to log in as you're doing, wait for the GIFT icon to appear in your game. Click on that and it will take to the website with your free gift. No log-in required - at least for me. 

Where exactly do I find the cookie site page on my comp?

Try clearing whatever existing cookies you have for this site, then Refresh and choose Accept All.
