If only some of your potential matches are far away, there are a few reasons why this might be:
Discovery Settings – We may sometimes show you potential matches that fall slightly outside your preferences. Although they’re a bit farther away, we hope you agree they’re worth the exception. To double-check your distance preferences: tap the profile icon > Settings > scroll to Discovery > see Maximum Distance.
Travelling – If you have recently visited another city, you may see people from there for up to 24hrs after changing your location.
If you think this is more of a technical issue, you may want to try these troubleshooting steps:
Log out and log back in by tapping the profile icon > Settings > scroll down and tap Logout.
Delete the Fruitz app and reinstall it.
