Students unable to login with same login in used all year.
Of my classroom of 22, approx. 1/4 received a message that their login in was incorrect but we are all logging in using Google, which is linked to their school account and the same way we have been logging in all year without issue. Of the 1/4 several got in by simply 'spamming' Duolingo by rapidly and repeatedly clicking on the google log in button. 2 students who were unable to get in with that method got in through googling the tiny cards, and 'spamming' Duolingo then entering into the Duolingo site by clicking the link at the bottom of the screen. What's up Duolingo?
