How do i unlock the contributor badge?

Question

It says "leave a comment with 5 upvote" which i have done, but it's still not unlocked.

Answer 1

ok

Answer 2

The comment doesn't mean the answers u give in Q/A forum
This has to do with commenting in the lesson session and getting five upvotes

Answer 3

Sometimes it takes time to update the badges. If it is still locked after maybe 3 days, contact SoloLearn. Before you contact them, make sure that you didn't like the comment on your own and counted your like.

Answer 4

Complaint to sololearn using in-app feedback feature or [e-mail] mail them.
