Thank you all for the information and discussion. I am also one of those affected. It's frustrating, because I am locked out of making anything new because I originally organized with stacks of Notebooks and Notes.
I have about 10 notebooks, and about 21 notes, and now I can't create either because my notebooks are over their limit. It's nice that I haven't lost anything, but being suddenly unable to make additional notes is frustrating.
Moreso, its frustrating it shows nothing to tell me how to fix it. It just continues to pop up requesting I pay a lot of money for the unlimited. I don't mind paying for subscriptions, I do for a few writing programs, but I've only been a driver of this product for a few months.
