H4 Interview Waiver

I am planning to visit India and will have to go through stamping.

From the travel.gov site, per the interview waiver eligibility expansion extended until Dec 2023, I could not find the criteria of “most recent visa must be issued on or after your 14th birthday”. Wondering whether this will make my H4 dependent child whose is above 14yrs now, and whose previous visa was before the 14th birthday, eligible for the interview waiver and drop box even though the usatraveldocs site asks the question for drop box eligibility? Please let me know if anyone has any information related to this.

Note that IW is at the discretion of the consular officer. If the child is applying with both parents, they may be eligible for dropbox.
If the consulate wants to interview they will issue 221g.
