On the big banner on the front page the features are usually exchanged every 24 hours. However, these days they tend to remain up to 3 days.
On the app, the categories change every 7 days (rising star, binge worthy and so on).
The carousel in the discover area is a mystery to me. Someone said the titles switch as soon as they reach a certain amount of subscribers. I doubt that tho, but I don’t see a clear time span either. Sometimes they switch weekly, sometimes monthly, then bi-weekly.
I think it’s only taken care of when the person in charge finds the time for it
Those are my observations. However, in the past weeks the categories hardly switched. Not sure if they’ll remain on that vague schedule or if they return to the usual schedule
