Why there are some courses like Kotlin that u can't download for offline reading??

Answer 1

The Kotlin tutorial is user generated. The app is not setup to download user generated lessons.

Answer 2

Because sololearn only allows you to download programming courses.

And I guess kotlin is just a small tutorial not a complete course. 😎

Answer 3

When the Kotlin course is completed, it is likely that SoloLearn will make it a fully supported course like they did with the C language.
