RAF Doesn't Work

Was asked by GM to post here after submitting a ticket, but the RAF link doesn’t work as intended. Me and my GF want to play together via WOW, so I sent her my RAF link. She clicked the link and afterwards it asks her to either log in or to create an account. She created an account, but afterwards, it gives her the error: “Whoops! Something’s wrong with your link.” When she clicks it again, after clearing cookies and cache on her browser, she then clicks log into existing account, but after logging in, it shows the same issue. We used a different browser, incognito mode, clearing the cache again, but nothing works. Hoping to get this resolved before the 7 days, so that we can get the rewards.

I am also having this issue.
