Tell that to Apple engineering team who hasn’t been able to fix iCloud tab syncs after all this decade or so. Among hundreds of bugs that Apple users just live with, some even defend. Something tells me things in Apple’s OS architecture is so messily intertwined and too many things hardcoded that even competent software engineers at Apple will start having nightmares at the thought of touching them. Perils of a completely closed ecosystem (and don’t mean closed source).
