Thanks for this thread. I can definitely say that here are the most important 2 points that might interest you!
1. The screenshots are generated when you go to a page in Edit mode and do a change there. The system then fires an event and our screenshot service takes the latest screenshot
2. In some cases these page thumbnails are used as an Open Graph images when posting the page to the social media. When you update the OG image of a specific page from the SEO app, the system overrides the page thumbnail immediately.
I will pass this to the product team to check if there is smth wrong with your website that stops new screenshot to generate.
Best of luck,
I am having the same issues as stated above. I have gone into the SEO app and manually added a screenshot of my current page into the image in the page menu, however that has not corrected the issue. I have been continually making edits to all of my pages in edit mode but none have automatically updated their screenshots from the template they started as. Additionally, I have added a new main page to my site and it has no thumbnail what so ever in the pages app or the SEO app.
I dont know if it is unrelated or not, but there are red exclamation marks next to all of the page titles in the SEO app.
