I had assumed it is by definition instant?

Surely anything else would imply a mechanism with additional complexity and indirectly void the entire concept. Delayed entanglement effect doesn't quite have the same cleanness for lack of better word

Entanglement is like splitting a coin in half, so you have a tails and a head half. Then you put one in your left pocket and give the other to a friend.

Then, just by looking in your left pocket, you can learn that your friend has the heads half—instantly!

In other words, it’s not as spooky as it is made out to be.
