Do causal principles apply to timelike entanglement and quantum superposition of orders?

[Rene Kail]

Are timelike entanglement and experiments demonstrating causal non-separability by quantum superposition of causal orders an indication that causal principles may not be applicable to quantum mechanics?

It's possible. But there are other explanations too.
