I'd like to report something that has been happening with me for the last few days.
Ever since I started studying Python here I noticed that sometimes whenever I'd click "Submit & Save" and later "Start Next Lesson", I'd skip the next lesson.
It just happened while I was doing the "How to use APIs with Python" course, the 7th lesson (Anatomy of a Request) was skipped and it went to the 8th lesson (Making a POST Request).
I strongly believe it's not my mouse because even if it was, I couldn't skip a lesson without getting the code to work properly, unless there was no need to code something which is not the case here.
Note: My OS is Windows 10 and I use Google Chrome to access the Codecademy and the forums.
