Not really a problem but more of a nit-pick. when I get on the mobile phone , I'm stuck with a downgrade. I mean ,sure, all the features are there but put a few little things don't appear like the name of the last post on the forum hub. And the size the screen is forced in also gets to be a problem. I'm sorry, I'm just ranting.
I think it's because they just can't cram so much stuff into a such a proportionally smaller screen. If there's a 'switch to desktop view' button, I like to press that. But I've never been on this site on mobile, so I can't say for sure.
