@dj-designs sure you can request permissions in componentDidMount, or really anywhere else (as long as you’re requesting before you try to send any important notifications)
Are you saying that when you request permissions in your iOS app with await Permissions.askAsync(Permissions.NOTIFICATIONS), nothing happens?
If you’ve already granted the Expo app permissions to send notifications, you don’t need to ask again, so that would explain why it’s working in the Expo app. I recommended reading our push notifications guide end-to-end, it’s a huge help when implementing notifications into your app
