Thanks so much for the reply, Dan! Unfortunately, I don’t believe anything is positioned Absolute. The header is Fixed to be sticky, and wondered if that was causing an issue, but its height is not equal to how far off the anchor is landing. Just weird that it works on the second click, which also makes me think the viewport height is not being calculated correctly initially. I also made sure I didn’t have any weird interactions or anything causing an issue. I’m stumped. The even weirder thing is sometimes it randomly works on the first click after reloading. It worked for about an hour yesterday before breaking again (after I had told the client it was working, so not great). I have also reached out to support so will report back if I get an answer. Thanks again!!
Edit: I did have the video play button as Absolute so tried removing it but the issue remained.
