"Ingame step counter not working and neither adventure sync"

#PokemonGO: Hello everybody,my pokemon go stopped to register steps overall. It says that i did 0 steps/0 meters today wich obviously is wrong. No powersaveing or what so ever is on and PoGo has all premissions.Adventure sync does not work either (did never for me. Sometimes i got a few hundret meters but thats it). Is there a way to fix it by now? - Here again all powersaving options are off, all premissons are granted, pokemon is fully closed, the apps are connected aso.I also tried to use the huawai health app wich was synced to fit but it didn't change anything.​I got a huawai mate 10 pro with android 9​​Thanks in advance :) via /r/pokemongo http://bit.ly/2WFIljb
