Restaurant order app will not open or sign in? Protect orders before troubleshooting
“The order app will not open. What happens to orders already accepted?” Write down visible order numbers and progress before reinstalling anything. Avoid repeatedly guessing a password or resetting the tablet until you know which part failed.
This guide is for restaurant order devices in Japan. Steps vary by platform and device contract. We checked Uber Eats’ official merchant device recovery guide on 25 October 2026. Uber Eats.
Record accepted orders → check whether the store is online → separate network, app and sign-in faults → contact the provider
Keep accepted orders under control
If another device or dashboard shows the orders, assign one person to handle each order. A frozen app does not prove an order disappeared. If you cannot confirm whether new orders are arriving, ask merchant support how to pause intake safely.
Sort the symptom before changing settings
| Symptom | Check first | Next step |
|---|---|---|
| Other apps cannot connect either | Store internet, Wi-Fi and whether this device uses a SIM | Follow the network guide |
| Only the order app will not open | Storage, update notice and official app source | Check provider instructions for an update or reinstall |
| Sign-in screen blocks access | Account, permissions and authentication method | Use official support; do not share passwords |

Device → connection → app → account. Work from the earliest failing point instead of treating every symptom as hardware failure.
Before an update, reinstall or web fallback
Uber Eats describes installing its official order app from Google Play on Android and signing in. Check whether your device and contract follow that route. A factory reset can remove saved information: confirm accepted orders and recovery details first, then follow device-provider instructions. The web order manager may require its tab to stay open and may lack sounds or printer connection. Test orders, alerts and printing separately after switching.
Before buying another tablet
For a provider-supplied device, ask about replacement and supported models. For your own device, compare OS support, alerts, printer compatibility, connection method, support and recurring cost. A new tablet alone may not solve an account problem.
Sign in → online status → new order → accepted orders → alert sound → receipt printing. Check for duplicate handling.

Summary
Protect accepted orders first, then separate connection, app and account symptoms. Tell the contracted platform or device provider the error, time, device model and order status.
