The natural state is living immersed in a place where other beings are and spontaneously interacting with them without a developed ego/personality filtering the interaction, as the closest relatives to human (chimpanzees and bonobos) do.
This makes the socially-conditioned relationship model very unstable, since such a relationship will only work if, as long as and to the extent that the conditioned beliefs happen to match the other person and their beliefs.
Since the conditioned beliefs are fundamentally false (because they are of the form "you will be happy if X" but happiness is actually the absence of any such belief) they are unstable and they will mutate once their falsehood is partially realized, and this process, along with viral cultural propagation, also creates many different conditioned mindsets that make matching and intimacy very challenging.
So the problems with dating apps are just a very specific effect of what is the fundamental nature of human beings and reality.
