Something went wrong

Was working until 2/3 weeks ago. Then suddenly the message "Health unavailable" what I try to sync appears. Then if I try to open the Health Apple app not only I dont have the new data, but also all old ones are gone. If I turn off and on the phone, all data are back and i can also sync the new data from Firbit, but only for a short time until I get again the "Health unavailable" message and starts all over again. Really annoying for a paid app. The worst thing is that 2/3 weeks have passed and nothing has been done. I contacted the app support, they talked me to try the new 2.2 version: thanks, like if that wouldnt be the first thing I tried. Hugely disappointed.
