If you are experiencing constant crashes and network issues with the Weis Markets app, here are some comprehensive steps to troubleshoot and potentially resolve these problems:

1. Restart Your Device: Begin by restarting your iPhone. This can help clear temporary glitches that may be affecting app performance.

2. Check for App Updates: Ensure that you are using the latest version of the Weis Markets app. Go to the App Store, tap on your profile icon, scroll to see if there are updates available for the Weis Markets app, and tap "Update" if necessary.

3. Clear App Cache: While iOS does not allow direct clearing of app cache like Android, you can delete and reinstall the app, which helps clear any corrupt data. To do this, press and hold the app icon until it jiggles, tap the "X" to delete, and then reinstall it from the App Store.

4. Network Settings Reset: Sometimes, issues may arise from your network settings. You can reset these by going to Settings > General > Reset > Reset Network Settings. Note that this will erase saved Wi-Fi passwords, so be ready to reconnect.

5. Check Internet Connection: Verify that your internet connection is stable. You can test this by using another app to browse the web or check for any ongoing internet outages in your area.

6. Report the Issue: If the problem persists, report the issue to Weis Markets' customer support. You can provide them with detailed information about the crashes, and they may have specific solutions or be able to fix issues on their end.

7. Stay Updated on Known Issues: Frequently check the Weis Markets website for any announcements regarding app issues or maintenance that could be contributing to the crashes.

8. Reinstall the App: If crashes occur frequently, uninstall the app and then reinstall it from the App Store to ensure it runs with a fresh installation.

By following these steps, you should be able to address the crashes and network issues efficiently. If none of these methods work, the problem might be on the app's side, and waiting for an official update may be necessary.
