New web interface - Notebook disappeared

[WouterP 0]

@Mod: I'm struggling to find the right subcategory to place this in, please do put it in the right one.

I've switched to the new webinterface, and all of a sudden I can't see a notebook I've shared with my partner. In the old web interface, it reappears... How do I get it to appear in the new web interface?

Not a mod, but welcome to the forums. This is a good place for the question. Unfortunately, the answer is that in the current state of the Web beta, there isn't any way to address this from the user end. Problems with shared notebooks are among the known problems in the beta, which presumably they're working on addressing. Definitely a pain if you want to use the beta's slick new formatting features on notes in this shared notebook. See these existing threads:
