Here is what you can do:
- Have your partner create their own personal Feeld profile using their primary FB account.
- Go to Feeld Profile (human symbol in the bottom right) > 'Edit'.
- Tap on 'Invite your partner' and share the link with your partner (only one of you should perform this step).
- Feeld will open via the App Store or Google Play; your partner will need to accept the invite, and once they do, you'll be linked.
- To include your partner in one of your conversations, open the Connection in question, tap on the 3 dots in the top right-hand corner, and choose Add Partner.
