Problem:
Customer described the issue: I'm trying to add a NEW view to a page, which will be based on an existing view. But when I add a View block, I only get the choice to use an existing view, not to create a new one.
Solution:
Upon further review, we identified that the issue was the deactivation of the Toolset Access, somehow it was impacting in the permission of creating a new view directly from the gutenberg editor. After enabling it again the option became accessible once more.
