I nearly always use my mobile for MN and when banners like this appear they mean half the page is taken up with stuff. Plus there's no way to get rid of the banner (I don't want to click on it because that would make you think I liked it), and the same banners come up repeatedly when I'm logged in.
I know Tech are trying to have a clear out at the moment but it would be really, really lovely if you could put an opt-out in Customise or a big helpful cross to remove the banner on the mobile site? Please?
