Since the WordPress update I have not been able to edit posts in the block editor as haf way down each page, the blocks are blocked (!) by a series of drop down menus as in the image link.
Two of the these are related to plugins – Yoast and Ultimate Social Media. If I disable these the dropdowns disappear. One is, rather unfortunately, related to the theme I use, which is a real problem for such a large site.
But one of the dropdowns is actually for the post settings themselves. Which I can do nothing about as that’s an actual WP thing. Anyone else having this problem? Fixes, advice, anything would be good. I’ve temporarily went back to the classic editor but would rather have a proper fix. Many thanks.

@stuartahamilton Was the problem do to a conflict with the theme, as suggested on the forum ​topic?
