On Demand training courses are not part of the Premium or Standard Learning Zone subscription packages. They are part of the Enterprise Learning Subscription package however.
Thank you for getting back to my question.
However, on that web page it was said those courses available for both Premium and Enterprise. That is why I raised this question here.
I believe the web page has been edited recently. Google search cache still has a reference to the availability of on demand cources for Premium subscribers (wether this information was added by mistake).
Anyway, thanks for clarifying this to me.
Yes, we were able to correct the error after you pointed it out to us. Thank you for that.
