Google Calendar doesn't synchronize automatically. I can force sync in settings or calendar app, but if app is left alone it stucks, hours or even days behind online calendar.
I have Redmi 4X with xiaomi.eu stable 8.2.12.0. I also tried weekly builds (7.6.22_v8-7.1.zip).
I have system app "Google Calendar Sync", "Calendar" (from Xiaomi) and "Google Calendar".
I added all of them to exceptions in Battery Savings (by setting "No restrictions" for them) and nothing. Only manual sync.
Other services like Gmail and Contacts sync work. Better or worse, but work.
