On iPhone and iPad, the Contact app is still in preparation. Access is connected through the App Store client. These are not separate services: both accept the same link from the Contact account.
What to do once
- Get access in the yes.contact account.
- Copy the connection link.
- Install the Contact client or Incy from the App Store.
- Paste the link and turn protection on.
- Confirm the system permission for the new connection.
If one app is unavailable in your store region, install the other. The flow does not change. You can add the same link on a Mac if the plan still has a free device slot.
