I think the Apple software UI team has cultural problem in adhering to "one source of truth", and that's where most of the problems come from. I've seen this many many times throughout the years, from toggles, to actions, account creation (I have dupes from tapping a button too fast), etc: the UI doesn't match the internal state.

Another example is most any toggle that's linked to Apple cloud stuffs, like settings in your iCloud account or parental controls. You see it toggle immediately, but that's unrelated to the actual state. You can't know the actual state until you exit the page and go back. Meta gets this right with their apps: you toggle, the toggle turns disabled, then the toggle is re-enabled when the state is confirmed remote side.
