New firmware worked quite well for my S9P - until today. Forgot to activate navigation after starting my activity (stock trail running), probably too excited as it was a race, but I should not have tried to use a route after that. Watch froze on the route selection screen and crashed after that. Seems that recording stopped some time during the freeze, maybe the last mile/km S+ is to blame as everything works perfectly when I try now. On the upside, the S9P survived my rolling breakfall down the mountain without a scratch
