iCloud Calendar events not syncing from iPhone to MacBook

Events created in iCloud Calendar on iPhone are not syncing with iCloud Calendar on Macbook.

Events created on Mac are syncing to iPhone.


What's wrong?


The event is also not registered in Calendar on www.cloud.com

The error must therfor be on the iPhone.

I have IOS 26 on my iPhone.

On the iPhone, got to Settings > [your name] > iCloud and double check that Calendar is turned on. If it already is, turn it off, choose to keep you events, restart your iPhone and turn Calendar back on. (you'll probably be asked to merge the events; do so.)
