*Huawei is extremely inventive in breaking apps on their devices. In addition to all the non-standard power management measures, they introduced a new task killer app build right into EMUI 9 on Android Pie. It is called PowerGenie and it kills all apps that are not on its whitelist. You cannot add custom apps on their pre-defined whitelist. This means there is no other way to fix proper app functionality on Huawei than uninstalling PowerGenie as described here.
