Here's what you can do:
1. Re-install both of your Feeld profiles.
2. Go to Feeld Settings → Edit profile → Pair Profile.
3. On both profiles tap "-" beside the Pending Invite.
4. Tap on “Invite Partner” and share the link with your partner.
5. Once your partner follows the link and accepts the invitation, your accounts will be linked.
In some cases it takes up to 24 hours for profiles to pair.
