Most couples on Feeld use Paired profiles. This means they each operate unique accounts, and link them. However, some people still use our old couple account set-up, from back when it was possible to create a couple account on one device.
So, in a nutshell, if you see someone cute but can't click on their partner, it's because they've got the old account style.
They might be authentic, or they might be a scheming single dude. Listen to your gut (and other messages from below the belt), but report any dodgy interactions to our Support team - we take community safety seriously.
