I started moving from Evernote to Notebook recently, using the Mac app. I imported several notebooks and all was well. Then suddenly the app started crashing within seconds of opening it. I tried to uninstall it and reinstall it, but I must not have found all the files that needed to be deleted because it still shows my notebooks when I open it (had I totally uninstalled it, I assume I'd need to log in again). I don't know what else I can do, so please help me troubleshoot this. Otherwise, I can't use Notebook because I really need to have access via the Mac app.
