Tried everything, magisk core mode only, checked it in magisk hide along with play store and Google framework as well, cleared it's data and cache, even uninstalled and reinstalled it. Nothing worked. Actually quit working on 16.2 but I waited for an update to fix it. Only thing that helped was uninstalling magisk, but even after registering again and reinstalling magisk, it again quits and says can't be used on this device as it isn't certified (which it shows certified).
