Why some links to lessons are not available from the mobile application?

Question

Somebody asked a question "What is C++?" and I wanted to provide a link to the lesson. But I found out that the "Copy link" button is disabled. A link to the PHP "Introduction" lesson is also disabled.

Update: now it works 😊

Answer 1

If it was available before this, best bet is that SoloLearn is restructuring the lesson link IDs and have to temporarily disable some links to specific sections in a lesson. It is also greyed out on my side. Honestly, I have no idea. We can always find out by contacting SL, but of course, you already know that.

Answer 2

Works on my mobile with no problem.
