How to use programming hub app with pro? Does it actually open all courses?

Answer 1

I think you have to contact on programming hub support.
This is Sololearn and if you have problem with Sololearn then you can send mail on [email protected]

Answer 2

The last time I tried Scamming Hub, near the half of the courses were 'in development' (inaccessible) and the Python one was for Python 2.
That was about a year ago. So I suppose this is what you get there with 'pro'.
