the new floating massive ad is TERRIBLE, whose idea was this? who are the designers and developers working on tumblr? what is your problem? just fix the stuff we ask you to, there's no need for new features and don't fix what's not broken. the app constantly refreshes and goes to a previous page when scrolling through a blog or a hashtag. i'll be 10 minutes down someone blog then suddenly i'm on my dashboard again or on a previous post! what the heck! this is why i stick to the desktop version.
