Welcomes Terrace Sin
can you provide us with exact MIUI umber your on.
if you need to you can disable auto updates by going to Google play store, profile in top right, Settings, General, Auto-Update Apps

I'm currently on MIUI Global 12.0.1, totally skipped the recent update thinking it might make everything worse.
This doesn't happen only when Google is updating my apps, as I said, it happens whenever I'm downloading something, so disabling auto-updates won't necessarily solve the problem...
