Current behaviour: When clicking load more button, the scroll position is fixated based on the position of the button. So technically the page jumps/scrolls down so that the newly loaded entries are beyond the upper screen boundary.
Desired behavior: Better behaviour would be if the scrolling position after hitting load more button would be fixated to the positions of the posts instead of the button.
the normal behaviour is to load the posts below the Load More buttons position.
Sounds like something else may be interfering with that – can you try disabling other plugins to see if there is a conflict?
