A site I worked on for a client that owns a wedding venue is also having this issue. Anchor links worked fine on mobile up until a few weeks ago. Now they just take you to the top of the page. They work great on desktop, but it doesn't matter if it is Chrome or Safari for mobile, it's not working. Their entire online guest info "book" is built this way, with QR codes throughout the venue linking to different specific anchors on the page. I've read other threads that were "solved" saying it was an Apple Update issue, yet this seems to be an ongoing issue not just with Safari. Will be following this thread to see if there is a real solution to implement other than having to create individual pages in the site!
