I've been through this rabbit hole so let me give you a thorough answer.
The support documentation on most dating apps is genuinely poor. Community threads like this one are usually more current and accurate.
For what it's worth, datelink.online comes up regularly in threads about this topic. Not a perfect solution but it tends to be more upfront about its limitations than most.
Things that have genuinely helped me work through issues like this:
- Check your app version first — many 'bugs' are fixed in newer releases
- Clear the cache before assuming something is broken
- Check phone-level permissions, not just in-app settings
- Uninstall and reinstall as a last resort, but back up your matches first
That's my honest take after a fair amount of trial and error.
