Stuck in Lesson 13 of foundation training

Dear Team,

I have completed lesson 12 including quizzes, after that, I accidentally clicked on Lesson 1 Quiz, and after that, all upcoming lesson till 12 or more got locked automatically due to which i am unable to move forward with the tutorial.
Can you help me with this?


Have you tried completing Lesson 1 Quiz again? I’m sure after that’s passed (again), the rest of the lessons will unlock
