My render distance is so low

So the problem is, my render distance is really low. My maximum render distance, before the  Caves and Cliffs update used to be around 18. Now, after the update, it is 9. I really don’t understand, because my other iPad, which is the same model, has a higher render distance than mine. My other iPad has 14 chunks of render distance AFTER the Caves and Cliffs update. My iPad is very capable, and I don’t understand why it has a lower render distance.
