Android companion thread credentials you don't have any credentials to import

Thread Preferred Network SLZB Ultima 3 used for android and ios… and Google TV Streamer. Syncing in devices and services Thread takes forever and returns “you don’t have any credentials to import” Is there a fix because nothing that is shown on the web seems to work for me.

You then need to have the credentials on the phone in the first place.

If you want it the other way around then follow this.
