I'm on iPad Pro 2020 running Evernote 10 on iPadOS 14. I'm a paid Evernote user on the middle tier right now so I get to enjoy lots and lots of "please upgrade" buttons all over the interface on all my Evernotes. On Evernote 10 most of the time it goes to a screen that either says "oops, we encountered an error..." and has no way to go back to the main interface and I have to crash the app.
Really seems like it wasn't tested throughly before releasing to us.
