Family sharing invite issue

Hi, is second family member part of the Family Sharing Group? Do they have Apple Cash in their Wallet App? Is their iPhone updated to iOS 14.6 (this is a common issue)? Updated their Apple ID age to 18/21? Here is a list of common possible issues,

1. all iPhones must be iOS 14.6 or higher
2. turn off VPN
3. log out and in to your Apple ID
4. ask Participants and/or Co-owner to log out and into their Apple ID
5. make sure you and participants are currently in US.
6. make sure Participants and Co-owner has Apple Cash setup in Wallet App
7. Family Group members should update their age in Apple ID. >> https://support.apple.com/en-us/HT204164
8. Participant must be using same Apple ID they use for Family Sharing Group
9. Two factor authentication must be turned on
10. Restart iPhone after performing any of the above

‘It may be necessary to delete the invite and their reinvite to share the Apple Card.

Your welcome. I’m glad you got it worked out. I’ll reword point 9 to include the password. Thanks for the solution and reply.
