Why are my Cal.com bookings getting cancelled?

How would I know the day it starts?
- Feder reads the bookings made and the bookings kept in Cal.com each day and compares each day with your own history.
- It tells you when bookings go quiet or either number moves outside its usual range.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See what Feder reads from Cal.com, which feeds Wins. Feder only reads. It never changes anything in Cal.com.
