I'm thinking about upgrading my iPad to iPadOS 18, but I wanted to confirm, if I upgrade to iPadOS 18, will my notes be accessible in the Notes app on Mac Sonoma? Because I remember once that I upgraded my iPad before my Mac, the upgraded iPadOS upgraded all my notes (in iCloud) in the Notes app, and when I tried to access these same notes through the Notes app in my Mac, it just said that the notes aren't compatible with the old mac Notes app version and with old Mac OS version, and it requested me to upgraded my Mac OS. I wanted to ask, if somebody has already for example upgraded their iPad or iPhone to 18, but is still using Sonoma on their Mac, so can you can still access the same notes (in iCloud) from all your devices. And how does the Math Notes show up in the Sonoma? Are those notes just empty?
