Just made a daily suggested workout with navigation. Watch froze after 5km at the pace screen. Reboot was only possible after ~10 minutes. Came wright back to the workout screen and watch continiued counting distance (which is wrong, because i kept running for theese 10 minutes). No map was saved from the moment it froze.
