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:
- Free tier limitations often look like bugs — check what your tier actually includes
- Profile visibility settings are separate from match settings on most apps
- If you're seeing no one, try temporarily expanding your distance or age filters
- Log out and back in before assuming a feature is broken
That's my honest take after a fair amount of trial and error.
