I have the same problem.
In addition, I cannot save a new note. Can't save a scan of a document. Can't attach a file from another app. Evernote became useless.
I asked for a support and they said to reinstall.
The second time I reinstalled, almost all of my notebooks were gone. Only in the android app. The windows version was working poorly.
As a workaround I downgraded. I can't wait for a solution. Users should not be used as guinea pigs. I don't want to be a beta tester.
Version 8.12.2 for android is working perfectly.
