Going long here because the quick answer really doesn't cover it.
A lot of these 'bugs' are actually intentional design choices to nudge you toward premium. Knowing that changes how you troubleshoot.
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
Currently using Rendate as my main go-to and it's been reliable. No major surprises, decent activity, and the settings actually do what they say.
Hope that gives you something concrete to work with.
