Family Sharing invalidates user guides
I changed SIM Cards recently and iMessage no longer works.
all guides are for an account that isn’t part of Family Sharing.
Family Sharing changes how accounts are managed, and there is no guide I’ve found to work around this.
Example: iMessage is turned on and the toggle is greyed out. To re-enable it, the only solution I’ve found is to sign out and back in, signing out isn’t an option like it is for a non-family sharing account
