Neither is really update worthy, but this late in the cycle it couldn’t hurt to let schools you’re still waiting on an II from know that you’re still interested. If you interviewed with the school already, don’t send the update.
When did you last communicate with the school? I agree it probably won't move the needle. Be mindful of any instructions you had at your interview day about updates. Some schools will limit you, while others will let you submit as many as you want.
