Hello
I don’t have a preference for a short term or a Gutenberg block. However, the proposed demo uses the short term. In general, these starter kits are aimed at novices, including myself. So, it is disturbing when the installation carried out does not obtain the expected result, suggesting an obsolescence of the product.
The short term was functional in version 2.1.7. Now identified the problem, I think it would be good to make this short term functional in a future update of the plugin.
