Hi there! I'm sorry to hear you're experiencing a blank screen issue with Travelzoo. That can be really frustrating! Let's work together to troubleshoot this.

1. Refresh the App: First, try closing the Travelzoo app completely. Swipe up from the bottom of your iPhone screen and swipe away the app. Then reopen it to see if that resolves the problem.

2. Check Internet Connection: Make sure you have a stable internet connection. You can try switching between Wi-Fi and mobile data to see if that helps.

3. Clear App Cache: Sometimes, clearing the app's cache can fix loading issues. Unfortunately, iOS doesn't allow direct cache clearing, but you can uninstall and then reinstall the Travelzoo app. This often resolves persistent problems.

4. Software Update: Ensure your iPhone is running the latest version of iOS. Go to Settings > General > Software Update to check if any updates are available.

5. Disable Any VPNs: If you’re using a VPN, try disconnecting it temporarily and see if that resolves the issue.

If none of these steps resolve the issue, there may be a temporary outage or issue with the Travelzoo service. You might want to check their support page for any announcements or further troubleshooting tips here 1 or feel free to reach out to Travelzoo support directly.
