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

[https://homey.app/no-no/flow/-zR3Em/](https://homey.app/no-no/flow/-zR3Em/)

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