I exported some notebooks from an account and imported them another account by .enex files.
When I have finished import a file, I could open imported notes. However, few minutes later, the notes disappeared from the notebook. (Only the notebook was left with no contents.)
Is this error of the app?
I use Evernote for Mac (10.36.4).
I am a free member.
I tried some .enex files and they were all under 60MB.
