View Distance is 6 instead of 14 even after restarting!

In MCPE 1.1, I used to be able to play @ 14 Chunks on my iPhone 6S.
In MCPE 1.2, I had to RESTART my iPhone every now and then to play at 14 Chunks!

In MCPE 1.2.1.. Things became even worse!
I can no longer play at 14 Chunks even after restarting!!

Fix this, PLEASE!
Also why is the iPhone 6S not listed in devices? Only 6 and 7 are listed..

Thanks
Regards
