Don't worry, you're off the hook! 😄
It's bizarre to pay full perpetual price and not have access to the learning resource.
I'd be a bit wary about going onto Ciniversity much knowing it'll be taken away.
LinkedIn Learning is good as they actively update C4D tutorials, Pluralsight haven't updated C4D really in a few years and Greyscalegorilla is too expensive subscription model for a hobbyist tbh.
It's sad that the access to the knowledge is behind so many different pay walls.
