Hi there! Thanks for reaching out about the "System Error, try again later" message you see when tapping Order Summary in the Express Scripts app. That sounds like it’s preventing you from viewing your order details properly. Before we dig a little deeper, can I ask a couple of quick questions?

- Are you connected to Wi-Fi or using mobile data when this happens?
- Have you tried closing the app completely and reopening it?
- Have you checked if the app needs any updates from the App Store?

This type of error can sometimes be related to server issues or app glitches, so I'd like to start with some simple checks. Here's what we can do step-by-step:

1. Close and Restart the App: On your iPhone (iOS 18.6), swipe up from the bottom of the screen and pause in the middle; then swipe up on the Express Scripts app card to close it. Open it again and try Order Summary.

2. Check for Updates: Open the App Store, tap your profile icon, and scroll to see if Express Scripts has an update. If yes, update and retry.

3. Toggle Network Connection: Switch between Wi-Fi and cellular data, or turn Airplane Mode on/off to refresh your network connection.

4. Restart Your iPhone: Sometimes a simple restart can clear temporary errors.

If these steps don’t help, the issue might be on Express Scripts’ end, as some users have reported a similar "system error" when trying to perform certain app functions, possibly due to temporary server-side problems1.

If the problem persists after trying these, I can guide you through reinstalling the app or help you contact their support directly. Let me know how these initial steps work for you!
