Hi Jim,
Re 365 doesn't have subscription issue, it doesn't coming when I use onedrive. I don't really use onedrive. I mentioned it because after i logged into onedrive on my browser, OneNOTE does not work any longer.
I don't want OneNote to work with Office 365. I have my notes stored in my personal OneDrive with microsoft account and it has always worked when I was on my windows machine. I even worked on my mac after installing it and running it for a month or two now. But only recently, it started to not work, and the issues such as menu bar has no options, cannot use 'command' functions (Eg. 'command q, command c, command v...etc.' while in OneNote, and many others appeared.
