Why is my courses locked? Do I jave to become a pro user?

Answer 1

Nah, you don't have to be a pro user to do normal courses. Some code coaches are pro but not the complete course. I guess you just missed a lesson and trying to do the next. Make your you've completed the previous lesson before going to next

Answer 2

Bro, You Don't Need Pro For Courses...
Also, You Can Try to Repair:
1) Update Sololearn To The Latest Version.
2) Force Stop The App
3) Restart Your Phone
4) Open The App

If This Doesn't Work, You Login On The Web Version Of Sololearn on PC.
If It Still Doesn't Work: Then, Report This Error...

Answer 3

Got the same for Java course
