We have curently disabled the Layout menu but it does not mean that we have removed it permanently. This change is temporary and the menu will be back in a couple of weeks. In the meantime you can take full advantage of our new Layout Builder.
With this new feature you will be able to create your own layout, you can add blocks, split those blocks into columns and you can also add new sections, everything with just a few clicks.
Please let us know if you have any comments or questions.
All the best,
