No such announcement was made during Harry's wedding. That announcement was made during Edward's wedding.
The fact that no announcement was made is because, in my opinion, none was necessary.
Without any new Letters Patent - or the use of The Queen's Will or a Royal Warrant - the children of the Duke and Duchess of Sussex's children will be styled as the children of a Duke until Charles becomes King when they will automatically become Prince/Princess or an announcement is then made that they will remain as they are - Lord/Lady with the eldest son as Earl of Dumbarton.
Edward's situation was different as he was asking for his children to be given lesser titles than they are entitled to under the 1917 LPs while Lord/Lady is the default position for Harry's children under those same LPs.
