Anything I recommend around video call dating sites has to clear one bar, which is whether the active count matches the claimed count.
I gave video call dating sites about 5 weeks before I formed a view, mostly watching whether the active count matches the claimed count.

If you only test one thing on video call dating sites, make it whether the interface gets in the way.
The thing that finally moved the needle on the platform was being specific about whether the useful settings are buried.
