I was able to import all my notes from Evernote to the desktop app including all the notebooks. The problem is with the android terminal application. I was able to syncronize all the notes using One Drive but the Notebooks are not in the terminal version and all the notes are without classification in one only list.
What software or method did you use to both export your data from Evernote and import it into joplin? If you do it correctly you should have a separate notebook for each notebook you had in evernote.
I used a special backup program that I got from GitHub to download an export all of my Evernote notebooks.
Then they imported into individual notebooks. Let me know if you need help.
Thanks, fortunately I finally see my notebooks in my android device. The remaining problem is that my windows desktop app and my android appp don't syncronize automaticaly. To syncronize, I have to go, in my windows desktop, to advance sync and choose "recharge local data to sync target". With this action, Iater, I can see my updates from the desktop also in my android app, but obviously I am loosing the opposite updates that I did in my the android device. Something is not working properly. I am syncronizing though my onedrive account.
