Amazfit Watch faces

How can I replace a watch face bin that I uploaded, for instance when I have an improved version? I can't find a edit button.

Go to "My uploads" section

then

click "Edit this watchface"

or go to the wf page and

click "Edit this watchface"

I found that section, but it says :

You do not have any uploaded Watch Faces.

Any suggestions?

Please, re-login. It should help.

Yes, thanks!
