Auto-Send with no cancel option

I just downloaded it to get photos from my mother-in-law and it asked me to title a "moment" and when I hit create it automatically sent it to the people in the photos and would not let me cancel. So because someone was in 1 photo they just got 107 of mine from a trip and there was no way for me to stop it
