works, but with quirks
Buying and installing was super easy, I was kind of expecting it to fail tbh, so I’m very pleasantly surprised. I also just received an official email from Microsoft, so that tells me I’m truly an official customer 🙂 The quirks are that some tools (spell check specifically) have reverted to their old Office versions instead of the new ones. It’s been happening gradually and it’s odd. However, nothing that bothers me too much, so I’m really happy overall.
