New iOS 15 update makes site hard to use

Hi FB team, I updated my iPhone to iOS 15 yesterday and noticed that the menu on your site when I use Safari isn't useable anymore! When I click the hamburger button the menu appears, but I'm unable to click on any of the links. What's weird is that I can use the menu that appears when I click the circle with my initial (the menu that has the dashboard, calendar, my programs, etc.). I suppose it could just be my phone, but it seems like a problem with the new upgrade so I wanted to let you know. Hopefully it's an easy fix!
