In my store I have three product pages. On mobile devices when the top product page is clicked nothing happens. If you hold it and open it in a new tab, it opens. I changed the order of the pages and this happens for all three of my product pages when they are in the first position, only on mobile devices. I do not have this issue on the desktop version.
I even tried adding a 4th (blank) page at the top just as a placeholder. That didn’t fix it. The top page with items still didn’t work.
