Pop-ups not working

Site URL: https://www.polaritycode.com/

Hello. The five pop-ups on my site used to work, but are no longer working. For an example, go to polaritycode.com and try clicking on the "With Unbound Spirit - Credits" button. This used to generate a pop-up that would show the user more information about the song, but it no longer appears to be working. Can anyone help me figure out why? Thanks!

Where do you experience it not working? I can see them fine here:

Very strange. It doesn't work for me on desktop for Chrome or Safari. It also doesn't work on my iPhone. But it does work when I go to incognito mode on Chrome (desktop). Any idea why this is?

[I also had a few others try it and it wasn't working for them either.]

Any other thoughts on this? It still doesn't appear to be working.

I just checked it and it's working for me on mobile and desktop. Maybe try a cache clear?

Thanks! That seemed to have solved the issue on desktop, but I'm still seeing the issue on mobile. I tried clearing the cache for Safari on my phone and also disabled "Block Pop-ups" in the Safari settings, but it's still not working. Any idea why?

Any update on this? It still doesn't appear to be working on mobile for me. Thank you.
