Amazfit Watch faces

Same problem here with GTR 47. Not sure if it cames with the last update. Now when I try to download a new face, the app shows a button with the "Start discovery" text on it. When you push it you have a error msg & nothing more

Hi.
I've received some support from the app guys, & it worked!
You have to:
- Enable device visibility in Amazfit (you can turn it off after installing the watchface).
- Use direct installation without spoofing the file.
Tx again.
