Can't Access Some Notebooks

[DianeE 0]

At least one of my Notebooks just gets a notice "Sorry, we're having some trouble. Try reloading the page" so I can't access it at all.  OI have to go to the website to access the notes I have in there.

At one point I got that message and couldn't get out of it at all so I had to reinstall the app.  

The whole thing is just buggy as all get out and has turned something I used without thinking about it into a nightmare.  I use Evernote for EVERYTHING and now it is a struggle.  Can we get the old app back?
