Hey, everyone! New Goodnotes user here. I recently bought what I believe to be the unlocked version of Goodnotes 5 to be able to have more than 3 notebooks. However, when I check the version in the app, it says 6.0.8; does this mean I have Goodnotes 6? What's confusing to me is that I get this button at the top of the home page task bar that says I can "Try Goodnotes 6 for free".

Would love to know what version I'm really using since I'm cross-checking it with my recent bank transactions that tell me I made two purchases from Apple. I'm trying to make sure I didn't make an additional payment before I go to my bank and try to dispute the transaction.
