We purchased a DJI Mini 3 Pro and powered it on.
After that, we purchased a DJI Care Refresh (2-Year Plan).
In the DJI controller, there was a warning that we needed to activate the service plan within 48 hours. Clicking on that option would require an activation code.
DJI did not send us an activation code with the purchase of the service plan.
We used https://service.dji.com/djicare/coverage to verify that our purchase was valid, but no information on the activation code was available.
From the controller, we want to the profile settings and unbound the drone. After we bound it again, the Replacement Service was marked as valid.
