They lowered the chunk display options to just 13 when they could be more before

Hello how are you?
 I write this message to say that in this latest update of minecraft bedrock, on my device (ipad air 4) under the chunks display option drastically, before this update the game ran correctly and without low fps, even with worlds with The activated function of mountain and cave experiments.
 I hope that the chunks option can be increased again to increase it more and have a better gaming experience on this device.
