What is ''in beta''?
I want to learn Hindi and I've just started. But it's in beta yet, so do I better learn later? I mean will the new subjects be added afterwards?
It actually does not mean it is available for desktop only; that is separate. It means the course is new and the errors reported per user rate has not dropped below a specific threshold for an extended period of time. I think the Japanese and Korean courses were only available on mobile for some time before being released to desktop.
