Chime Snooze not showing up in App

Hello, my family has four members, everyone with an iOS device. I’m noticing that the Chime Snooze option under devices is only showing on two of the four phones.Is there a setting or limit to the number of devices that can snooze a chime?It’s important that I figure this out because the people in my household that I want to have the snooze capability are my kids (young adults) that tend to come home when everyone is asleep. Being able to snooze the Chime (for 15mins) keeps the dog from barking and waking up the entire household.
