Custom blocks does not work on MCPE 1.16 Beta

You might be experiencing MCPE-63121, can you try removing register_to_creative_menu from the block's JSON file?

I try that but keep without working

Do you have experimental gameplay on?

Yes, whenever I create a new world, I turn on the experimental gameplay

Everyone complains about this mistake, because they installed addons does not load the blocks

Do you mind attaching the affected add-on here?

I have created and special test addon and uploaded it to this page

Not all of your components were using the right values, I've attached a correct version, you'll also want to turn on experimental gameplay for now

Oh ok, I'm gonna try that, thank you.

The custom block shows up for me in the '/give' command list in Beta 1.16.100.59 after I replaced the original tb_test_block.json inside the Test Block.mcaddon with the one provided by Gruntastic. Closing as Cannot Reproduce.
