Unfortunately, I have a problem with the use of Apple Calendar: When I invite someone to an event (iCloud Calendar), they do not receive a notification and cannot agree to the event. However, when someone else invites me, I directly receive a push notification that allows me to join the event.
I also have a similar problem in the Photos app. When I create a shared album and invite people, they do not receive an invitation and cannot join the album. However, if someone else creates the album and invites me, I see that invitation and everything works.
These issues occur on all of my iOS devices iPhone XR, iPad & MacBook Pro (with current software).
Ultimately, outgoing invitations of any kind do not arrive, while incoming invitations work fine. Does anyone have any ideas as to what this could be?
Thanks for the help in advance.
