A. Ensure that your internet connection is stable. Try switching between Wi-Fi and mobile data to see if the issue persists. If the app continues to fail, restart your device and try again.

B. Clear the app's cache by going to your iPhone's Settings > General > iPhone Storage > Wetherspoon > Offload App. This will remove the app but keep its documents and data. Reinstall the app from the App Store to see if this resolves the issue.
