What you are seeing

A freshly inserted macro sits on a placeholder for a long time before showing content.

#Why it happens

The document exists but has not been indexed yet, so the macro retries every 15 seconds up to 10 times. About two and a half minutes.

Wait, then refresh the page. If it never resolves, reopen the macro config and save the content again.

Setting	Where	What it does
Global settings → Capabilities → Markdow	-	Hiding Markdown removes it from the Capable nav bar and the content byline menu across the site (app property capable-global-hidden-capabilities). It does NOT stop existing macros from rendering.

Large-document scroll mode	500,000 characters	Past this the document macro shows '⚠️ Large content detected. Rendering in scrollable mode.' and renders inside a fixed 1200px-high scroll box instead of inline.
Virtualised rendering threshold	500,000 chars ; 1,000,000 chars (large p	Above the threshold the document is chunked (400 lines or 60,000 characters per chunk, fences kept intact) and only visible chunks are rendered.
Macro title and description input length	50 characters each	The macro config's 'Markdown title' and 'Markdown description' fields and the from-scratch editor's title field all stop at 50 characters.

Two separate reasons. First, the title strip only renders when 'Show Border' is on. With t

The save path never passes the description through, even though the underlying store accep
