No new profiles around you? Expanding your search criteria will allow you to see a wider range of profiles, especially if you're located in a remote area. Open Tinder > tap the profile icon > Settings > Discovery Settings > increase the age range and search radius.
If you think there may be some technical trouble, you can try logging out back into Tinder. Tap the profile icon on the main screen > Settings > scroll down and tap Logout.
If you have tried all of the above and still don’t see anyone, please check back at a later time.
