Linking MDE Accounts - Help?

I have had an MDE account and have listed my husband as family. This is the account I have the reservation, ADRs and FPP under. I have now set up his own account on MDE under his name so we can look up things on his phone. But I can’t figure out how to get the reservations and things to show up under his MDE account. It comes back and says that there already is an account on this reservation number. What did I do wrong? Can I fix it? Or should I just have him log in on his phone under my account? TIA!

Under the account with all the plans, go to ‘family and friends’ and add your hubby. Use the email associated w his account. Pretty sure he’ll receive and email and have to confirm your friendship. Once that’s done, it’s been my experience that all the plans show up on all the accounts. Did this w my wife and multiple friends w no issues.
