I feel like I have to pick and choose the "good stuff" from macOS and iOS days instead of having confidence that everything inside works well. Case in point - I tried recently to migrate from Gmail/Google Calendar to iCloud Mail and Calendar and use Apple's own apps for that. No matter what I did, I could not get calendar invitations to actually appear in the inbox in Calendar for me to RSVP appropriately. All I got was an email with the RSVP buttons in it that allowed my response to show up in the organizer's calendar, but it added nothing to my own calendar. (And yes I did go into the iCloud Calendar settings and tried both the app notifications and email notifications for incoming calendar invites)<p>Reminders and Notes work great. Everything else, not so much.
