DU site/Safari Browser issue on iPhone iOS [View all]

I have noticed that beginning this week, some of the DU control buttons no longer function on my mobile device using Safari (iPhone X, latest iOS). Specifically Rec, bookmark and certain DU specific links e.g. searching users for Inmail. When any of these buttons are "pressed" it acts as a home button of sorts and takes me to the top of whatever page or thread I am on.

I'm not sure if it is an HTML5 thing w the site or what, but I have zero issues on any other webpage.

I tried clearing the cache and no luck. If I use the Google App for search and browse on my phone these buttons work fine - leading me to believe that it's a Safari for mobile iOS or a DU site problem.

Is anyone else experiencing this issue?
