In reply to Lee.

There exist 272 open bugs, and more are under consideration (e.g. labled "need testing") being a bug or not, and you are telling us, all works fine?
In total there are 1,385 open issues.

If anyone has technical problems with Gutenberg they are very likely caused by 3rd party plugins or themes that are awaiting compatibility updates.
And no, most of the reportes issues are with clean installation, either the recend development version or clean wp 4.9.8 with recent Gutenberg version.

Use the block classic for example, insert text, insert an image, the image will jump to top - every image will jump to the beginning. Or search on github issues for list or table and read, and test.
