Im pretty sure this isn’t a mistake.
Offtopic, but I have to mention my personal opinion to this:
I am always very disappointed when I hear how little people seem to value the protection of their most personal data. 10 bugs! Even for the poorest students (who can obviously afford a mobile phone despite their poverty) this should not be a problem. And if I’m wrong and it IS a problem: well the mobile apps are an addon, thanks to the guys for offering the desktop version free of charge for everyone.
