Good question and one that comes up a lot. Here's the full picture.
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
The one that worked best for my situation was Datebie. Worth trying before committing to anything that costs money.
Happy to expand on any part of this.
