As someone who has used various kinds of LMS, I am impressed with the power, simplicity, and flexibility packed into Marble. The fact that one can easily organize existing content into an online course is a major advantage.

However, the support leaves much to be desired. Email was not answered and live chat was not responsive even though agents appeared to be online. I waited for the whole day before writing this review, knowing that the team might be very busy; but still, I have not received a response.

The Marble Academy is also not as helpful as expected. Some videos are outdated as they appear to have been created for an earlier version of the platform which is different from the current platform in very significant ways.

More importantly, the CNAME feature is not working as described. Even after setting it up and confirming that it has propagated, the subdomain simply brings up a Heroku page instead of showing the Marble Academy that was set as the destination.

I was excited about Marble and was going to recommend it to others but now, I have to hold on. If users cannot receive the needed support at this relatively early phase, how can one be assured of excellent support over the long term? I hope the team will look into these issues and do the needful.
