Due to the US government restrictions, new Huawei device models made available to the public after May 16, 2019, will not be able to utilize Google's apps and services. 

Because we use Google services in the EasyWork app. New Huawei phones may have EasyWork app user experience issues, including not being able to use the map. Modules like Attendance and Mileage Tracking that use the Google service to track your current location might be malfunctioning.

We are sorry for this inconvenience and are exploring solutions. In the meantime, you can find more information directly from Google here: https://support.google.com/android/thread/29434011?hl=en
