Open Settings → Apps → Phone → Call Blocking & Identification and turn on Kansel. If it is already on, switch it off and on again, then open Kansel and tap “Update”. Remember that iOS always lets calls from your saved contacts through.

Open Kansel → Protection and make sure Kansel is set as your call-screening app (Settings → Apps → Default apps → Caller ID & spam app). If you use another caller-ID app, note that Android only allows one at a time.

The list refreshes in the background once a day (more often with Pro). You can refresh it manually with the “Update” button on the home screen. If that fails, check your connection and make sure battery saver is not stopping Kansel from running in the background.

In Kansel's Settings tap “Restore subscription”, and make sure you are signed in with the same Apple or Google account you subscribed with. Pro unlocks once the store confirms the payment, which can take a few minutes.

If the number is on your personal list, remove it from “My list”. If it is on the community list, its owner can submit a request on the appeal page.

Inside the app: Settings → Account → Delete account. Full details are on the delete account page.
