Can't Access Lesson 3 of Slang Skill
I've completed every lesson in the tree, including Slang 4 and 5, which I accessed via URL, but whenever I try to start lesson 3, it just takes me back to the main page. What's happening there?
Eventually I just tested out, but that took a lot of trial and error. It would have been better to complete the skill the normal way.
I did this (copying each sentence to a file as I went along) and was eventually able to test out and finish the tree today.
I was able to access the fourth and fifth lessons at https://www.duolingo.com/skill/vi/Informal-Expressions/4 and https://www.duolingo.com/skill/vi/Informal-Expressions/5 and it said I completed the skill so I didn't have to test out.
That's weird, the skill didn't go gold for me until I tested out. I think it did say that I'd learned it after lesson 5, but it didn't go gold. I think it was just programmed to say that because it's supposed to be the last lesson you do.
It was the same for me. I finished lesson 5 and it said "completed", but when I went back to the tree it still showed only 2/5.
