We are sorry about any inconvenience caused to anyone who purchased the Legacy Version Mac app when they had already bought GoodNotes for iOS. Note: the Legacy Version Mac app is no longer available on the Mac App Store.
We'd like to share that while working on this universal version, we had several technical limitations along the way, and we weren't certain that we could offer it to our users sooner. If you recently bought GoodNotes 5 for Mac (Legacy Version), we'd advise requesting a refund from Apple. Please note that all refund requests are handled by Apple and not by developers, so if the refund page states that you need to contact us instead, you're probably not eligible for a refund anymore. If that's the case, we recommend using a different refund reason, or contacting Apple support by phone to explain your situation in more detail.
