2. Conflict between MIUI and Google Calendar

One of the most common causes of failure is the conflict between the built-in MIUI calendar and Google Calendar. On Redmi 4 with MIUI 8/9 firmware, this is especially true as the system tries to duplicate events, which leads to errors.

Date and time errors
