Recently (can't be more exact but probably the last couple of weeks) the mobile site has been awful for me. It's been slow to load, when I scroll down the page hasn't loaded properly so I get a white screen which I have to wait to catch up (then if I need to scroll back up I need to wait again) and sometimes it becomes completely unresponsive and I have to reload the website to get it working properly again. It's only Mumsnet that I'm having problems with. iPhone and on Safari.
