Do not worry as we are here to help. Are you using the web app or mobile? What Os is this (Android/iOS)? Did you try that on a different device? Would you mind sharing the screenshot, if possible? Also, please make sure that you are accessing the correct tutorial link. Kindly write us back with any observations.
For a reason (maybe my account automatically update), I have the "Learn" part under the "Library", which didn't appear before. Anyways, thank you for your responding so fast and if I have further questions, I'm happy to chat with you.
