Stopped working:( – Mi Heart rate - be fit Review

BAD UPDATE! Was working perfectly with runtastic before update. now HR only works for about 10 mins when running (i payed for premium version). Also it wiped out data from the band for couple days and nothing appears in mifit app for rhose days. Please fix. Loved this app, but now its a crap:(
