Isometric Tilemap sorting does not work in chunk mode

Following the instructions from both here: https://blogs.unity3d.com/2019/03/18/isometric-2d-environments-with-tilemap/ as well as here https://forum.unity.com/threads/isometric-tilemap-sorting-issues.554914/

I can not get the tilemap to sort correctly in chunk mode. It works fine in individual mode, but the performance loss is (obviously) immense.

Is this a bug, or is the information in the thread/blog post just wrong

edit: I found a dev more or less saying that youre just intended to use Individual mode. This is rather ridiculous as it defeats the whole purpose of using a tilemap in the first place. There is no reason (apart from a horrible underlying architecture) this should be the case.
