I have a blog but I got a message from Google Console:
Page partially loaded
Not all page resources could be loaded. This can affect how Google sees and understands your page. Fix availability problems for any resources that can affect how Google understands your page.
I have 33 blog posts and seems like 11 of them have the issue. Might be related to my 'embedded Youtube videos'.
But I've uploaded all the content the same way in all blogs.
