Hi! I understand you're having trouble seeing departures and arrivals under the dates in the Booking.com Pulse app on your iPhone. Let's get to the bottom of this together.

First, to better assist you, could you tell me:

1. Is this issue happening for all bookings, or just some specific ones or dates?
2. Have you recently updated the Pulse app or your iOS version before this started?
3. Have you tried any steps already, like restarting the app or your phone?

Meanwhile, here are some straightforward things we can try:

1. Restart the Pulse App: Close the app completely by swiping it away from the app switcher, then open it again.
2. Check Internet Connection: Make sure your iPhone has a stable internet connection, Wi-Fi or cellular.
3. Update the App: Go to the App Store and check if there’s an update available for Pulse. Sometimes display issues are fixed in updates.
4. Log Out and Back In: Sometimes refreshing your login helps. Log out of your Pulse app, then log back in.
5. App Permissions: Verify that the app has permission to access your calendar or notifications if it uses those to show arrivals/departures.

If none of these help, I can guide you through checking settings related to reservation restrictions or any filters that might be hiding arrivals or departures, as this occasionally causes those details not to display.

Let me know what you find after these steps or if you already tried any of them!
