In this example, I have added some Lorem ipsum content spanning a few paragraphs. I then converted these paragraphs from the Classic Editor to the new WordPress Blocks.

Note: This process will work for any changes made to the page/post, not just the Classic to Block conversion.

Over on the right-hand side you will need to ensure that a block is not selected OR you need to ensure that you have clicked on Document instead of Block. You will then see "Revisions" along with a number, which is displaying the total number of revisions/autosaves that it has captured and stored. Please click on "Revisions" to view the available revisions.

When you are ready to proceed, please click on the Next Page button below.
