Hi,
Thanks for your answer.
When I hit the button the first time, it scrolls down to halfway down the section, with most of the content hidden under the sticky header. However, the url generated is as shown in the hidden content, with the section ID added. When I then scroll back up to the top of the page and hit the button again, it slides back down to a perfect position. I have tried this in Chrome, Edge and Firefox, with exactly the same results.
I am stuck what to do. I have shown the button url and the section ID in the hidden content,
Thanks
