Always loses sync

Works great when it is connected, but the app always "cant find my mi band" even when it right on my wrist and has been right near my phone all day. Only fix is to unpair and pair again which causes me to lose all my steps recorded by the band. Seems like an app issue since my phone still says the band is connected via Bluetooth. Please fix!!
