When I try to place a new order the website doesnt allow me to add an item to the cart and for the orders I already placed when try to check the status it takes me to the referral program home page.
I just used it an hour ago from my laptop (US). You can go here: https://lucidmotors.com/portal/referral-program. then click on "visit rewards store" mid-page. no issues. you can also click the hamburger menu on the web site or in your phone app and select the specific category and it should work. anyway it let me add items to a cart and then check out using rewards points.
