Going long here because the quick answer really doesn't cover it.
Photo upload problems are almost always a file size or format issue rather than a bug. JPEG under 5MB tends to work everywhere.
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
Currently using Datenest as my main go-to and it's been reliable. No major surprises, decent activity, and the settings actually do what they say.
That's my honest take after a fair amount of trial and error.
