Does the Instinct 3 solar/E get calendar notifications (iOS)

I’m currently torn on the instinct 3 solar and E. I don’t need much, gps and smart pay mean nothing to me. they seem the same in terms of sensors for health tracking. my big question is if there is any difference in calendar notifications? I use an iPhone and the native apple calendar app. I’m seeing varying answers online on if one or the other can sync a calendar, some reports of them syncing but not actually delivering notifications? Not clear if it was an android or iOS issue either from what I saw.

can anyone attest first hand?
