Hi there! I understand you're having trouble with the QuikTrip app not starting the fuel pump and just buffering. Let's see if we can figure this out together.

First, could you please let me know if you're connected to Wi-Fi or using mobile data? Additionally, have you noticed any error messages or just the buffering issue?

Here are a few steps to try while we troubleshoot:

1. Check Your Connection:
- If you're on Wi-Fi, try switching to mobile data (or vice versa) to see if that resolves the issue.

2. Close and Reopen the App:
- Sometimes, closing the app completely and then reopening it can resolve issues. You can do this by swiping up from the bottom of the screen (or double-tapping the Home button) and swipe the QuikTrip app off the screen.

3. Restart Your iPhone:
- A simple restart might refresh the app functionality. Just hold down the power button until you see the "slide to power off" slider, then restart your device.

4. Update the App:
- Go to the App Store, check if there is an update available for the QuikTrip app, and install it if applicable.

5. Clear App Cache:
- Sometimes, clearing cache can help. You can do this by uninstalling and reinstalling the app. Just tap and hold the app icon, then delete it and reinstall it from the App Store.

If you've already tried these steps or if the issue continues, it might be due to a protective measure at the pump, such as a delay related to leak detection or network issues affecting the app's ability to connect.

If the problem persists, we can explore other options or escalate it further. Just let me know how it's going! Are you satisfied with the steps so far?
