Hi Maigul,
I'm sorry you're having a difficult time. From what I can see, your Learn About videos are working fine. I am including a screenshot for your reference to make sure you can locate them properly. They can be found by clicking Learning > Learning Resources > My Professional Development > Certificates.
If you still have issues, don't hesitate to contact our Customer Support team!
All the best,
