Google Docs enhances Markdown support with new import, export, and conversion features
After first introducing expanded support for composing with Markdown in Google Docs on the web in 2022, Google has just announced that it's now introducing highly-requested features to enhance Docs' interoperability with other Markdown supporting tools. The new features include the ability to convert Markdown to Docs content on paste, copy Docs content as Markdown, export a Google Doc as a Markdown file, and import Markdown files as Docs.
These additions are particularly beneficial for technical content writers. For instance, developers can now collaborate on software documentation within Docs and then export it as Markdown for use in other tools that support the format.
The import and export options are enabled by default. However, the “Copy as Markdown” and “Paste from Markdown” options are off by default and can be activated by navigating to Tools Preferences Enable Markdown within Docs.

I don't see a "Enable Markdown within Docs" option for me, only "Automatically detect Markdown" which sounds different. Is this a rolling release thing?
