In this page, a private video is linked which takes users to video unavailable page on YouTube.

We can simply remove the video link containing sentence or add the appropriate link which is not private.

Example text link is taking user to video unavailable page on YouTube.

Open two browser windows, one with the test instructions (either A, B or C) and one with the Gutenberg editor loaded with the Twenty Seventeen theme. Example setup here.

Thanks for the report, @nhrrob. Indeed, that private link and much of the Gutenberg plugin focused testing content is outdated, and could use a freshening up.

For instance, I don't believe the Test team performs or reviews observational usability tests as described here. These were originally utilized when the block editor was relatively new, and the core UX was in its early stages of development. Issues and test reports for the editor are much more specific and succinct nowadays.

I'd like to see the purpose and content of these pages revisited, possibly with the workflow outlined in #24.
