I intend to buy a GTR4 (limited edition). A selling point, however, is that I can design my own watchfaces, as I have already done with my GTR2 (which is unfortunately defective after a year with a bootloop). Is that possible with wachface editor for GTR3? Or is there another editor available?

Hello. Today I created my first watchface with the great editor (thanks SashaCX75).
No I have the problem, that my WF were overwritten on watch. I think the problem is the same WF-ID.
How can iÍ creat a unique ID for my own WF?

Could someone help me please?
