[TUTORIAL] Trigger a flow using calendar events

Tutorials

Hi.
Any Idea why the following Flow won’t work? :

https://homey.app/no-no/flow/-zR3Em/

This one does work:
https://homey.app/no-no/flow/ovy4Em/

The only difference that I can see is that one is triggered on event start, and the other on event ends.

Calendat is syncing with homey just fine.
