Supposedly, I've removed downloaded update using instructions from https://wiki.rossmanngroup.com/wiki/Pixel_4a_Battery_Performance_Program#Restoring_battery_functionality https://wiki.rossmanngroup.com/wiki/Pixel_4a_Battery_Perform... - hopefully this will stop popups: >Users can delete an already downloaded (and not yet installed) update: Settings -> Apps -> All Apps -> Google Play Services -> Storage and cache -> Manage Space and from there on delete all data through the "Clear all data" button.
