You're lucky. I tried the same thing a week ago on my m5pro. purchased outside of DJI. Couldn't add on dji care, and when I open the DJI Assistant 2, it laughs at me and am unable to do anything IRT service/repair.
Experienced a unscheduled landing event from 300ft with my Mini 4 pro, the camera gimbal wouldn't initialize after a tree impeded the unplanned landing. No DJI care was in place for the drone as it had been purchased used and didn't get it...
I sent my Mavic 4 Pro w heavy damage to DJI in Canada. They sent a replacement within 5 days including shipping time. I’ve seen posts in other groups that US turnaround was under 5 days as well. It probably depends on the model, inventory and issue.
A friend uses Adorama's Extend warranty and Protection plan since the DJI stoppage here. It cost more, only one total loss replacement, or as many repairs as needed until the cost equals the price of the drone.
Anyway, recently he sent a Mini 4...
