Trouble moving on from lesson 15.1

Question

I completed 15.1 lesson. But it won't unlock the lesson 15.2 and I completed 15.1 two times. Does anyone else have this problem?

Answer 1

Maria Nobile
15.2 looks to be a practice session for pro subscribers.

I note that you meet this requirement, so there must be another reason.

Possible reasons could be:
1. bug in app
2. subscription not valid
3. Haven't completed previous lessons / challenges

This is all guess work from me.

Answer 2

Which course?

Answer 3

Rik thank you for answering. I really appreciate you taking the time. I just kept going past the locked lessons and they became available once I learned the info. I was then able to complete the unlocked portion.

Answer 4

Hi thanks......it's the HTML course.
