My experience is quite different. Pre-pandemic I used to use Duolingo on my public transport commute and I had it more than once that I reached my daily goal only to notice the next day that it hadn't registered properly. This happened quite regularly and with my free account I could only have one streak freeze, so I occasionally lost my streak because of this. Another issue that caused me to lose my streak is when Duolingo says: "Sorry we encountered an error. Don't worry your streak will be safe." In my experience my streak was not safe. I don't mean to be too harsh with Duolingo, I think they get a lot of features just right. The streak thing, however, was just an annoyance for me. These failures made me temporarily quit several times. Even if you know you should not become upset about stupid internet points it still hurts when you feel it is not your fault.
