That’s almost precisely their business model.

Dating apps don’t exist to find you connections, they exist to keep you hooked. They’ll give you the bare minimum of opportunities necessary to make you think they’re viable, drag it out as long as possible, pressure you to pay for premium, and if they ever developed a matching system that worked well, they’d bury it to stop half their userbase from marrying each other and uninstalling the apps.
