Hi there @Young, 

Welcome to the Community! Happy to help! 

So the smart sending period for your push notifications will followhe same smart sending window settings you have set for your campaigns and flows. You can discover what this window is in your account settings and manually change it to whatever you want. 

Thanks for participating in the Community!

Hi @Young ,

In case you are still curious about push smart sending windows, you now can create a custom smart sending window for push that is distinct from email under your push notification settings. By default, the window is set to 24 hours. See our guide to understanding your push notification settings for more details.

Thanks,

Mark
