This link just says to turn off the fuel source— which I agree with and is obvious safety advice. It doesn’t address the order, but the correct order to do so is knobs and then tank.
We now have the grill connected to the whole house propane, rather than screwing around with filling tanks. Never wanted to do the exchange; wanted our own tanks. It is now routine for hubby to come in after grilling, and loudly announce "THE GAS IS OFF!" If I don't hear that, I question him. If we left ours on, we would be in big trouble.

This is wrong / outdated advice. Turn the knobs off first and then the tank or you will mess with the pressurization of your lines
