DJI Phantom 3/ DJI Go connection

I have a Phantom 3 standard that is not accepting my DJI Go password. Tried changing a few times. Any suggestions?

If you’re sure you’re entering the correct password, then reach out to DJI support for help.

Call call DJI support.

I thought that I heard the DJI no longer provided support for the Phantom 3 since it was older. Not true?
