@Awwcool22 I moved your post over to this existing thread: Switch to Premium Family while on Google sub
It looks like your wife's account is currently upgraded to Pandora Plus through Google Play - this would explain why she is currently unable to accept her invitation to join your Premium Family plan.
Joining or upgrading to a Pandora Premium Family subscription is currently not possible through third-party vendors (e.g., iTunes or Google Play). Before she can accept your invitation, she will first need to cancel her current subscription through Google Play and wait for it to expire. Once she begins to hear ads on her account again, she can then accept the invitation.
Hope this helps!
