The core idea of er the relation interpretation is that quantr mechanics is not telling us how system like an electon anatom, manifests itself to an observer. To you, not to a scientist, quanto mechanics is just telling how systems, physical system, manifest themselves to any other physical system. In this formulation, one does not talk about observation. One doesn't talk about a observer of measuring apparatus, or anything like that, but talks about relations between physical systems. If we put the interraction a relations first, then things go in order, and we we understand quanto mechanics.
