With iOS 18, TipKit got explicit support for syncing tip state via iCloud. However, before that, TipKit already did iCloud syncing implicitly, as far as I know.
How does the new explicit syncing relate to the previous mechanism? Do we have to enable iCloud syncing manually now to retain the functionality in iOS 18? Is there a way to sync with the state that was already stored by TipKit in iCloud on iOS 17?
