Hello! I understand you're having trouble managing your ReadyRefresh My Water+ delivery on your iPhone with iOS 18.6.2. I'd be happy to help you get this sorted out.

Could you please tell me a bit more about the issue? For example:
- Are you unable to log in to your account in the app?
- Is the delivery management section not loading or showing errors?
- Are you having problems changing, skipping, or rescheduling a delivery?
- Do you receive any specific error messages?

Once I have a bit more detail, I can guide you through the best steps to solve the problem.

The “manage delivery” tile doesn’t open

Thanks for clarifying that the “manage delivery” tile just isn't opening in the app on your iPhone. Let’s try a few things to get that working smoothly again.

1. Force Close and Reopen the App: Sometimes apps can get a bit stuck. Swipe up from the bottom of your screen (or double-click the home button if your iPhone has one), find the ReadyRefresh app, and swipe it away to close completely. Then reopen it and tap the “manage delivery” tile again.

2. Restart Your iPhone: This helps clear temporary glitches. Hold down the side button and either volume button, then slide to power off. Turn your phone back on and try the app again.

3. Check for App Updates: Go to the App Store, tap your profile icon at the top right, and scroll to see if ReadyRefresh has an update. If yes, install it and try the tile after.

4. Ensure Stable Internet Connection: Make sure you’re connected to Wi-Fi or cellular data with a good signal as the tile might need to load info from the server.

5. Reinstall the App: If the above don’t work, delete the ReadyRefresh app from your iPhone (press and hold app icon, then choose Remove App), then reinstall it from the App Store. This can clear corrupted files related to the tile.

Try these steps, and let me know if the “manage delivery” tile opens after. If it still doesn’t, I’ll help you with some advanced troubleshooting. How does that sound?
