progress not registered
Well in the last few minutes my progress is not being recorded. When a exercise is completed the browser either freezes or stays grayed out for several second. Then ,the next screen will show a yellow completion ribbon but no points will show up and no progression towards the next level will be made even though as I said not only the yellow ribbon will show on the completed exercise but the lesson unit circle become yellow when all its separate exercises was completed. So tree becomes more yellow but no points. This only happened today with this course but it was a problem with other new courses but was eventually corrected. Does this happen to other people or is it a problem with my keyboard driver?
I don't think there's anything the Klingon Mods or Contributors can do about that. Have you tried filing a bug report? https://support.duolingo.com/hc/en-us/articles/204728264-How-do-I-report-a-bug-
