I'm one of those stupid people, who don't see, where the "puzzle" is. There was a serious and well-formulated puzzle for Einstein, which was inadequately (for me not at all) answered by Bohr concerning entanglement, and it's not in the EPR paper (which Einstein didn't like, exactly because of its unclear philosophical rather than physical statements). For Einstein the real issue was "inseparability", i.e., the fact that entangled states can be prepared such that far-distant well-separable parts of a system (e.g., two photons in an entangled polarization-momentum Bell state such that you can measure clearly the single photons by putting detectors far away from each other), which for themselves are totally indetermined (the single photons have utmost indetermined polarization, i.e., they are ideally unpolarized) while they still have 100% certain correlations (e.g., in the polarization singlet state, if A measured "H", with certainty B measures "V" and vice versa).
Now, indeed, Einstein was right in criticizing the Copenhagen interpretation, at least those which add a "collapse assumption" as a physical process outside of the quantum theoretical description of the dynamics, in calling this "action at a distance". His proposal famously was that there might be "hidden variables" which are not observed (or maybe even not observable at all) but provide the probabilistic description of an underlying deterministic theory due to incomplete knowledge as in classical statistics.
Then Bell formulated this philosophical quibbles in terms of truly scientific question, i.e., he made a prediction under general assumptions about what he called "local realistic theories", which is basically the assumption that all observables are in fact determined but their values for a specific system are unknown due to the unobserved "hidden variables". This lead to his famous inequality, which however is contradicted by quantum theory precisely for entangled states we know call Bell states. Now the philosophical quibbles were formulated as an experimental challenge, i.e., a true scientific statement decidable by observations, and starting with Aspect et al the issue was resolved completely with very high accuracy and statistical significance in favor of quantum theory.
For me the problem is thus completely solved as far as QT as a natural science theory is concerned. We are indeed now a step further, being already in the middle of the transformation of an academic puzzle, which is now solved towards having now a theory applicable in the sense of engineering, i.e., the results are now used to construct new technology like quantum cryptography and quantum computers. As in the case of electricity and magnetism, for which Faraday predicted that once the politicians could take taxes for its use, there's a lot money invested with high prospect to earn a profit from it.
I find it bizzar in such a situation there are still people not satisfied with quantum theory because of these now solved philosophical quibbles. The real scientific puzzle is rather to find a consistent theory of the gravitational interaction than the philosophical headaches of Einstein and Bohr.
