It's not possible to see all of the profiles you've Liked or disliked.
If someone you’ve Liked Likes you back, they’ll become a Connection. But If they don’t, you can’t see their profile again. You can’t see profiles you’ve disliked again either.
There’s no way to reset your Likes and dislikes to bring those profiles back in Discover.
If you’re a Majestic Member who’s accidentally disliked a profile, you can use the Go Back feature to undo your most recent dislike.
