Feeling your frustration. This update is no good. I’ve had multiple sites having problems.
Generaly it seemed to go back to normal if I just change a bit of text (or just add a letter and than erase it), just to get the option of updating the page. But you have to do it for every single page.
Also having issues when I add images, they just dissapear. Would be grateful if anyone had some advice or if the developer fixed this.
