As of today, Java Edition1.16.1 is available to everyone, and the attribute follow_range still does not work properly. For example, even if a skeleton's follow range attribute is set to 40, it will still only detect players to attack within 16 blocks (its default value).
Once a player is detected by the skeleton, it will follow the player up to 40 blocks, but there is no way to currently allow the skeleton- or any other mob- to target another mob at a distance that is greater than the modified mob's default follow range. A lower value, however (3, for example), does work. A skeleton with a follow_range set to 3 will not follow or attempt to attack anything unless it is within 3 blocks.
This is a game issue that really only effects experienced players and map builders- however, the follow_range attribute is crucial for making custom maps and mobs and remains a major unresolved issue.
