I’m afraid your screencast works because it’s taken from a desktop emulating a mobile device. As I said in my starting post “Mobile menu works properly on mobile view from a desktop, but on smartphones and tablets pages don’t fully load. Progress stops at around 40-50% so neither sticky columns nor mobile menu work“. Please try it on a real mobile device and even on tablet. You will notice that mobile menu doesn’t show, the viewport just shrinks. Even in your video I can see the viewport shrinking for an instant right before opening the hamburger menu.

Sticky colomns don’t work on tablet ad in mobile landscape view because page don’t fully load. I have other websites in which they work regularly. Also the “go to top of the page” button doesn’t show. Did you try clicking on the menu hamburger, not just looking at it? It doesn’t respond. I can send a video if needed.

Ok, I understand, thank you.

That means I can use these predefined tag templates inside a Newspaper theme page by importing them?
