Hi Arie,

While troubleshooting a user’s flow, I think a triggercard is working “inverted”, so to speak.

In this case he wanted to get a notification when a timer, with a duration of 60s, ran for 10s.

It triggers after 50s.

Now, is the description the opposite of the card’s function, or is the card’s function the opposite of the description?

DMed to you as well.
