MicrosoftGuys, this is an incredibly frustrating new "feature"! I am absolutely aghast that anybody would push something so half-baked and buggy into a product. It is not good enough even for a beta. With its weak support for the format, if it manages to display a notebook at all, what I can see is in no way useful because half of the stuff is just missing. Larger notebooks don't open at all – they just keep loading forever.
The worst problem: I have assignments where students upload notebooks. With notebooks that do not display, there is now also no way to download them and open them locally so currently I have no way to grade their work unless they reupload the notebooks as URLs. How on earth did anybody think this is ready? Have you done no testing at all?
