When using the link field within a fieldgroup that is used in a acf-gutenberg-block, custom post types are not available to choose from.
They are however when we use the same field outside of the gutenberg context.
This may be related to a (solved) gutenberg issue:
https://github.com/WordPress/gutenberg/issues/2084
and
https://github.com/WordPress/gutenberg/pull/7894
Same happens with the link build in WYSIWYG Editor.
Any thoughts on this? I think it’s crucial for development with gutenberg blocks…
