Just gone from a mini2 to a 3 pro, what do i have to do in the new app , its still showing the mini2

Hello there. I am sorry for the trouble this has caused and thank you for reaching out. May we please know what is the model of the mobile device that you are using please and kindly please try to uninstall an reinstall the DJI Fly application ( https://www.dji.com/dji-fly ) to see if the issue will still persist? In addition, please sync all of your flight records before uninstalling the DJI Fly application on your mobile device for you not to loose your previous flight information. If the issue persist kindly please try using a different recommended mobile device for us to be able to isolate the said issue. Thank you.

Once you've registered your drone with DJI, on your account  -  if you're using a smartphone and controller to link to the drone,  the DJI Fly App should launch. If you're seeing the mini2 on the startup screen, swipe left (or right) until you come to the correct Icon for the Mini3Pro.
