Unfortunately we aren't able to merge existing albums at this time. If you'd like you and your partner to be parent members of a single shared album, one parent will need to delete their album and join the other.
For example, if you'd like to delete your album and join your partner's, please do the following:
1. Uninstall then reinstall the FamilyAlbum app on your device.
2. Ask your partner to invite you to their album by going to the Settings tab, tapping "Invite Family", then selecting "Partner".
3. Once you receive their invitation, tap the URL in step 2 to join their album.
