Two step verification to shared user old number

Hi thereMy wife can no longer access our account as a shared user as Ring keeps sending her a two step verification request to her old number which is no longer available.I can't see any other way (such as email) for us to get her access again.Resending an invite to the original email address reverts back to the two step verification which we can't action.Any way to mitigate this apart from using an entirely new email address which is a hassle?
