Recently updated to v 10.0.4, still as of today the most recent available in app store. Besides my major complaint below looks promising. (iPhone 8 plus, iOS 14.1, 8gb of 64gb available) Evernote user since 2012.
Complaint: I don't see my notebooks. At all.
I have notebooks in stacks, open a stack then see the notes in the stack but not the notebooks. That's a lot of notes to go through to find the note I'm looking for. Result is I can't use Evernote on my phone. At all.
I'm open to your letting me know how to see the notebooks, that I was wrong. Otherwise, really need this fixed.
It looks like this has been a rough launch by the comments above, but please please get this fixed.
