New post does not appear on AMP homepage after posting

I have posted a new post. New post is showing on regular homepage, but the post is not showing on AMP-version homepage.

I have AMP cache enabled, so I have cleared cache, but no change. I have turned off AMP cache from the options, but no change. I have also deactivated AMP cache from plugin, but no change. I have reenabled AMP cache, but no change.

It seems like only the AMP homepage is not updating for some reason. (I see the new post in the categories page.)

Kindly advise.

The page I need help with: [log in to see the link]
