Hi there! I’d be glad to help you with the issue you’re having with the Avis iPhone app. It sounds like you’re reaching a point in the app after entering your pick-up details, but then something goes wrong. Could you share a bit more about what happens next? For instance, do you see an error message, or does the app crash entirely?

While I gather more info on your issue, here are a few things you might try to resolve it:

1. Restart the App: Close the Avis app completely and then reopen it. Sometimes, a simple restart can fix minor glitches.

2. Check for Updates: Ensure that your app is updated to the latest version. Go to the App Store, search for the Avis app, and see if there's an update available.

3. Device Restart: Sometimes, rebooting your device can resolve performance issues.

4. Clear Cache/Data (if possible): If you have an option to clear the app's cache or data within your device settings, that can help.

If there's something specific happening, let me know, and we can dig deeper!
