Snackbar does not disappear on its own

[itorres-1]

According to the documentation:

Snackbars inform users of a process that an app has performed or will perform. They appear temporarily, towards the bottom of the screen. They shouldn’t interrupt the user experience, and they don’t require user input to disappear.

However, cannot get this to work on an iOS simulator (iPhone 14 Pro Max @ iOS 16.2), as in, it simply displays and does not disappear on its own, ever. There also doesn't appear to be a way to configure the duration. Am I missing something here? Here are some of my relevant dependencies:

• expo: ^47.0.13
• react: 18.1.0
• react-native: 0.70.5
• @react-native-material/core: ^1.3.7
