What happens
My render and simulation distance is set to 32 chunks, but when I get far away from the crops they stop growing despite being in render distance and start growing again when I go closer
What I expect
Simulation distance to determine the distance that the crops stop growing

Currently, block ticking is only affected by the simulation distance setting up to a maximum of 8 chunks. This comment by @unknown addresses this (you'll need to read the surrounding context though to see this). If you would like blocks further than eight chunks from the player to be ticked, then that is a feature request, judging by that comment.
Random tick distance has always been a fixed value regardless of simulation/render distance.
Given we now have an option for simulation distance it would make sense to have random ticks go out to simulation distance though.
