Having the same problems.

It started out as not being able to search, but the situation is quickly deteriorating and now I'm unable to open pretty much any email message.

Some content seems to briefly show up and then it quickly disappears and after that, it's as if cache has been invalidated and you can't get back into it.

Luckily for me the Drafts folder's showing, so I was able to send (well, I assume it's sent) the Single Most Important Email I need to send today, which I'd spent about half an hour getting right just as the interface imploded...

While the web UX is borked, mobile app is not impacted if you can fallback to that until they fix the web.
