When I got the 1.16.2 update I immediately tried to hang chains in their new configuration. I am unhappy to say that it did not work. They all hang vertically, however I press the block. Maybe i'm doing it wrong, but it is annoying.

I may very well be wrong, but... I'm pretty sure the platform that has used the sideways chain placement are all running in the java 1.16.2 version, not the bedrock codebase.
