Here’s what’s working for me so far:

1. Update acf-composer to 3.4.3+ – Fixes the “no support for this block type” issue.
2. Update ACF to 6.4.0.1+ – Fixes the “called too early” warning

(h/t to Michiel van Harten via Roots Discord)

Extra credit:

ACF blocks with a default alignment will no longer output alignment classes (.alignwide, .alignfull) if $supports['align'] is set to false.

Previously, this setup would apply the default alignment while hiding the alignment control in the editor UI.

Now, setting $supports['align'] to false fully disables alignment support, including outputting alignment classes.

To fix this, update affected blocks to specify at least one alignment option in $supports['align'].
