How to Fix the McDonald’s App Not Working on Android

When the McDonald’s app stops working on Android, users often face problems like login issues, screen errors, or app crashes. This is usually due to connectivity problems, especially with unstable Wi-Fi or public networks. Error codes like 10021 show there is a server communication problem, stopping users from logging in or placing orders.

Sometimes, the app might not work because it is outdated or because of corrupted cache files on the device.

Now that you know the causes, let’s discuss the solutions

1. Change the Internet to LTE

Before doing anything else, try switching your internet connection to LTE. This can fix app issues caused by weak or unreliable Wi-Fi. Public networks or poorly set-up routers often stop the McDonald’s app from connecting to servers, causing crashes or errors. LTE, a mobile data connection, avoids these problems and offers a more stable and steady internet source for smoother app use.

2. Re-login into the Application

Log out and back into the app to clear any bad data linked to your account. This process removes old or incorrect information and sets up a new connection with updated data, often fixing login, timeout, or syncing issues.

1. Tap your Profile name at the top of the navigation bar.

   

2. Tap Log Out at the bottom.

   

3. After logging out, enter your credentials to log back in and check if the issue is resolved.

3. Check for Server Outages

If the McDonald’s app isn’t working, check if their servers are down using sites like Downdetector. Server issues can block logins, orders, or content loading.

Note: You can also try launching and using the McDonald’s application on another mobile device. If it works perfectly there, it means there is a local problem with your application.

These downtimes are usually due to routine maintenance or genuine issues where the server has stopped working. The MTTR (Mean Time to Repair) is usually in minutes and at a maximum, a couple of hours. You can try launching the application later after ensuring the servers are up and running.

4. Clear Application Data

Clearing app data resets the app to its default state by erasing all files, cache, and settings stored on your device. Your account and data like rewards and order history stay safe on McDonald’s servers.

Note: You’ll need to log back into the app after clearing the data, but your information is not lost.

1. Open Settings and select Apps.
2. Find McDonald’s and tap Storage.
3. Tap Clear Data and Clear Cache.

   

4. Reopen the McDonald’s app and see if the issue is fixed.

Solution 5: Reinstalling the Application

If nothing else works, reinstalling the McDonald’s app is best. This removes corrupted files or settings causing issues. Reinstalling also gives you a clean, up-to-date app with the latest fixes. It’s a simple way to reset everything and start fresh.

Note: You will have to log back into the application with this solution.

1. Press and hold the McDonald’s app, then select Uninstall.
2. Go to the Play Store and search for McDonald’s.

   

3. Select Install.
4. Once installed, open the app and check if it works.

6. Use Hotline/Website to Order Food

If the McDonald’s app isn’t working and you want to order food, you can use the hotline or the McDelivery website. Search for the hotline or visit the McDelivery site for your country. After logging into your account, you can access the full menu and place an order for delivery, without dealing with app issues. This method avoids app crashes or login problems while still providing access to the same menu and promotions.

If you call the hotline, make sure to mention that your application is not working. Customer support may assist you in troubleshooting the application properly.
