RAF not working

I generated a recruit a friend link to invite some friends to play wow with me. When they click the link they get a message that says: ‘[My name] wants to play with you’ However when they login to their existing account (which has not played wow in over 24 months), they get an error message that says: Whoops! Something’s wrong with your link.

I have re-generated the link for them to test and they still get the same issue and it’s happening with multiple people. I have verified that my friends have not played wow in the past 24 months, they are not my recruiter (in the past).

I noticed a similar issue in CS issue: 1806245. It looks like blizzard had to fix on their side:

Wonder if someone might take a look for me?

Thank you,
