I've just got my watch and I found out that it does not have mode toggle option in the app and that the colour sections on the additional dial can't be used at all. Does yours watches have the same problem? Or is it the issue with app? Maybe it's limited to specific region...
GigzBy default they do nothing. I really don't know how u can personalise them. I think that now there are useless or mayby U can use them in goals area. But I don't know that for sure, just assuming.
