My first cruise since before COVID is over 30 days away (July 31). I just checked my phone app and was able to see several little video's (very nice, by the way!) under the safety tab.
I watched the Life Jacket Instructions, Emergency Horn, Additional Safety Tips, Medical Facility (not helpful, no floor listed even though I have cruised enough to know its usually on 2), and even the cute Luka and Mika video for kids. Are these the the safety videos that you are referring to? If so, I haven't had to wait until last minute to review them!
I have completed Check-In documentation if that makes any difference...
