    The app is dead. Use a browser and visit the site(s) instead. Will save lots of time and frustration. :) – ShaWiz Nov 26 '18 at 8:02
  • @ShadowWizard I respectfully disagree, the iOS app is still very useful to me. (Of course, if you can't sign up, it'll be a lot harder to do useful things with it.) – Glorfindel Nov 26 '18 at 8:05

    @Glorfindel well... be really careful to never log out. :) (seriously though... not fixing bugs, even critical as this one, means one thing: the app is 100% dead) – ShaWiz Nov 26 '18 at 8:19
  • The only thing they have to do is to fix the app token matched the back end authentication. – Dor Bar Nov 26 '18 at 8:30
