Shared calendar events not showing up

Hello, rayyychul.

To start us off, please take a look at this article and make sure that these are the steps you are following to share your Calendars between your devices: Share calendar accounts on Mac - Apple Support. Once those steps are checked off, make sure to restart both involved devices as that can help with unexpected syncing issues like this.

Shut down or restart your Mac - Apple Support

1. "On your Mac, choose Apple menu > Shut Down.
2. If you don’t want app windows that are open to reopen when your Mac restarts, deselect “Reopen windows when logging back in.”
3. A Mac is completely shut down when the screen is black. Some computers also don’t show an active power light or have any fan or drive noise."

Restart your iPhone - Apple Support

1. "Press and hold either volume button and the side button until the power-off slider appears.
2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."

Let us know if we can help with anything else at all or if this doesn't settle your issue. Thanks and have a fabulous day!
