I live in Belgium Europe to get the MS health app on my Lumia 925 (Win8.1 Cyan Dev preview)I had to change my phone's regional settings in to USA and the Band works fine but when I want to buy an other app from the store I can't use paypal or my Creditcard anymore , it has something to do with the regional settings and with the tax regulations of each country I guess . So if I want to buy an app I have to chance the regional settings in to Belgium and it works back . so each time I want to buy an app now I have to change the regional settings , and if I want the Band work properly i change it back to US . I hope MS will release the Band in Europe soon .
