I have tried to contact their support and ask for this, but somehow I forgot the exact steps to recreate it.
Could someone help me out? Was it the link to maps from the notification of calendar?
edit: ok found it. It looks like it is for events which are coming from google calendar down to Huawei calendar app.
I will test it and contact support.
edit 2: Correct. If the address is added on calendar.google.com and will be synced to Huawei P20Pro.
Once event is opened in Huawei Calendar app and the user will click on "Show on map" link underneath the address - it will open Chinese maps website.
I have opened a ticket with UK Huawei Support and provided them screenshots and small video
