Unfortunately no link.
But I’ll try to elaborate.
When adding a block in the editor it gives a preview error.
Switching to code editor I see that the following code is what was inserted
<!-- wp:structured-content/faq {"version":2} -->
<!-- wp:structured-content/faq-item /-->
<!-- /wp:structured-content/faq -->
Then – weirdly enough – when switching back to design editor the preview error has resolved itself. And when returning to code editor it looks correct.
<!-- wp:structured-content/faq {"version":2} -->
<!-- wp:structured-content/faq-item -->
<!-- wp:paragraph {"placeholder":"Enter your answer here"} -->
<p></p>
<!-- /wp:paragraph -->
<!-- /wp:structured-content/faq-item -->
<!-- /wp:structured-content/faq -->
It’s strange.
