Is also a pain that the “login” link seems to be about the last thing that gets rendered on the page, making me wait ages for the stupid ads to load, well on an iOS device at least.
Either you have an old iOS device, or you might want to check your internet connection.
There’s certainly no issue on my pad, and if I need to see the login box a bit more clearly, I double-tap the text area to zoom it out to full page width. Works every time.
I think I have to log back in about once a month, never bothered to check, it’s such a minor inconvenience, really.
