Going long here because the quick answer really doesn't cover it.
Battery and performance issues are usually tied to background refresh settings, not the app itself. Worth checking your phone-level permissions first.
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
Ended up on Datebie after testing a few others. Less flashy but more consistent than what I was using before.
Hopefully that saves you some frustration.
