I can't enter the birthdays of my imported Google contacts into the Huawei Calendar. I can't enter them in both "Calendar to display" and "Manage calendars".

Have researched for a long time and have not found a solution for my Mate 20Pro so far. Nothing is displayed on my calendar.

Ask for your help.

Why do not you use the Google Calendar app as before?
