Hi there! It sounds like you're having trouble opening the Zulily app on your iPhone. Let’s work through this together.

First, can you tell me if you’re getting any error messages when you try to open the app? Or does the app just not respond at all?

In the meantime, here are some steps we can try to get the app working:

1. Force-Close the App:
- Double-click the Home button (or swipe up from the bottom of the screen if your iPhone doesn’t have a Home button) to see all your open apps.
- Find the Zulily app and swipe it up to close it completely.

2. Restart Your iPhone:
- Press and hold the power button until you see the slider to turn off your iPhone. Slide it to turn off, then turn it back on after a few seconds.

3. Check for App Updates:
- Open the App Store and tap your profile icon at the top right. Scroll down to see if there's an update available for the Zulily app.

4. Reinstall the App:
- If updating doesn’t help, you might consider uninstalling the app. To do this, press and hold the Zulily app icon until you see the option to remove it. Then, reinstall it from the App Store.

If you try these steps and the app still doesn’t open, let me know, and we can dig into more advanced troubleshooting or check if there might be a server issue affecting Zulily right now.

Are you able to give those steps a try?
