I recently upgraded to a paid user and now I can't delete notebooks in any version across Mac, iOS or Web browser. I've logged out, deleted apps on all devices and reinstalled but it still doesn't work. The notebook disappears and then reappears after 2 seconds. The only workaround I found is to create a note in the notebook and then delete it and so far it seems to remain deleted. In addition, I set up 2 factor authentication - I use Google as my login but I never get asked for a verification code. Suffice to say this is not filling me with confidence and I'm wondering if I've wasted my money?
