As of the above two updates, the /fill and /setblock commands do not allow placing of block variants that require IDs, eg. birch planks (planks 2) & light blue concrete (concrete 3).

This applies to both in chat commands and command blocks.

As such, it is not possible to fill/place these blocks anymore, with the command reporting this error: "Syntax error: Unexpected "2" in "planks >>2<<""

This is really inconvenient for me, and those who use /fill to complete large builds. I sincerely hope item flattening for more items besides wool comes to Bedrock soon too.
