Checkpoints Passed Without Testing?
I just logged on Duolingo, and found that I had unlocked a massive amount of lessons (as if the checkpoints were passed), as well as one lesson I have never done up to 4 crowns. It was not like this yesterday and I never tested to pass these checkpoints.
Is this a glitch? I have been using a public computer for the past 2 weeks but I have been very careful to log out. It also says that I have not earned any experience today. Plus, if someone used my account, I feel like they would have had to know a ton of German as well as have had a lot of time to get to 4 crowns within the last few hours of the previous day.. It seems really unlikely.
Is there a way to revert back so that I don't have all of these unlocked? My practices will be inaccurate and I won't be able to track my progress for the lesson with 4 crowns.
