Does the MS White authorized user card have an offer?

Authorized user offers are honestly all over the place. Instead of chasing old magic links, it's better to first check whether your primary card account has an authorized user invitation pushed directly by the system — a lot of people see it pop up right after logging in. Also, authorized user offers are often mutually exclusive with the primary card's sign-up bonus, or they require the authorized user to spend within a set timeframe, so don't lose the primary card's bonus just to chase an offer.

Magic links usually stop working because the target changed.

If the additional card is added but never activated, or if the spending requirement isn't met, will this kind of offer be revoked outright? Does it count as part of the sign-up bonus?
