It is 100% meant to mismatch you to keep you on the app to make money. Start asking people who met people on apps and you quickly notice a pattern. The person they are with was not like any of the other people it matches you with. It's not that hard to match people. They are betting that two people won't compare their apps after they get together. I have watched three couples in the same room compare their apps with each other, with all three realizing it only works by mistake.
