I had a look at the ID verification as I wanted to respond to a thread in the offers forum, the problem is nothing seems to load on the ID verification page (the one with the "click me when finished" button).
Nothing loads on Chrome/Edge across 2 separate PC's (ad block disabled), nor on Firefox on my Android phone.
Google dev tools shows this in the console:
