Depending on your Instant Pot model and the pan’s thickness, the cheesecake might need to be cooked more time. How to check if it is done: the edges should become yellow, and only a small part in the center should be jiggling if you shake it gently. If a large area is jiggling, the cheesecake is not done yet. In this case, cook it for another 10 minutes and release the pressure naturally for 15 minutes.
