I have updated all my apps to Evernote 10.0.4. Yes I'm running Evernote on iOS. And it is as you say, I went to the web version and my notes are in the web version. The app still seems buggy. I wrote an email to support about the bugs that I'm seeing. I will copy that email and put it in this post. I like what I'm seeing. But I do see bugs.
Email I sent to support:
Thank you for getting back to me. I updated to 10.0.4. The update did seem to make the loss of data problems stop. But there seem to be other issues the with thee app.
Notes disappear when I start to do a lot of searching. I’ll start a search and get the results. But after two or there times of refining the results, the notes disappear or even the app freezes.
Internal links do not seem to work like they should. I will have to close out off the note or even close the app and then reopen the app, to make the links work.
The internal annotation app in Evernote does not seem to work on annotations that were created in older version of Evernote. I can create and annotate new PDFs in the newest version of Evernote. But there seems to be a bridge that is missing from the old to the new .
Thanks Evernote team and best wishes.
