Extrem lag and low render distance on iOS devices between 2014-2015

The game has hit a massive low. It’s unplayable, lags all the time and worse of all u can literally only seen 10 blocks infrot of you which is the max render distance of 6 where did the other 10 go? I will demand a total refund on this or some kind of compensation because this is not a cheap iOS game if it is not fix in 1.2.1
