I'm playing MCPE on a Samaung Galaxy A3 (2016).
I have this problem:
animals stop following me while I have their fovourite food in my hand when they jump down or on a block, so when they change their altitude.
For example I have hay in my hand and a sheep. It follows me till I jump down or on a block, and so, when it has to jump too, it loses interest in food and stops following me.
