Amazfit Watch faces

Really, it's a contact issue!!!!

I clean the contacts with strong chemical and the contact is back, intermittent, but managed to upload all the faces I like to the watch.

Thanks for the advice.

I have been having this problem for quite sometime, my PC just don't recognize the Stratos. I have tried the following methods but it does not work:
1) Clean the contact pins.
2) Use different PC with different windows
3) Use different charging pod
4) Reset the Stratos.

All the above dis not work ...
