Problem: The user is building Blocks to be used by his users in the block editor. He expected to have a "max-width" when we create blocks with the Desktop view.
Solution: We removed the max-width for Desktop, as long as the Toolset Editor Max Width option is active. Can you check if it's active on the sites, which are not working as expected? It should be off (see screenshot) and then your max-width for Desktop should be applied again.
