2nd hand Spark doesn't connect with iPhone.
I've connected my Spark watch with my account first, and I found out that the previous owner didn't put it back to factory settings. I got her stats in my account etc. So when I connected the Spark again I putted it back to factory settings. The watch does connect to my laptop, and I named it different. But it refuse to connect to my iPhone, it still finds the old watch name and then keeps on in the connecting loop.
Absolute legend who can help me out!
