• If the McDonald's app is not working on your iPhone or Android, there are several ways you can solve the problem.

McDonald's has a mobile app that you can use to place orders for pickup or delivery as well as claim deals and rewards. But you might occasionally encounter problems using the app. Sometimes these errors are the fault of the McDonald's servers, or the issue could be with your own phone or app. Here are seven ways to troubleshoot the McDonald's app so you can get it working again. 

Turn off your WiFi

Perhaps the single most common problem people run into when using the McDonald's app is connectivity issues. If you're using a public WiFi network (perhaps even at a McDonald's restaurant), a low-quality connection might be interfering with the app. Swipe down from the top of the screen to see the Control Center or shortcut panel and tap the WiFi icon to temporarily disable it. Then try using the app again.

Restart the McDonald's app

It's also possible that your McDonald's app is misbehaving. Just force the app to close and then restart it — that may fix the problem. Here is how to close an app on Android and how to close an app on iPhone.

Sign out and in again

If there's some corrupt data cached in the McDonald's app related to your account information, another likely fix is to sign out of your account within the app and then sign in again. In the McDonald's app, tap More at the bottom of the screen and then tap Profile. To the right of your account name, tap Sign out. Then return to the More menu to sign back in.

See if the McDonald's app servers are online

For the McDonald's app to work properly, it needs to communicate with the restaurant's online service. It's unusual for that service to be offline, but if you're still having trouble with the app, it's a possibility. To see if the problem resides with McDonald's rather than your app, check the McDonald's app status page at Downdetector. You can also search "is McDonald's app down" in your web browser.

Clear your app data

You might be encountering a problem with the McDonald's app's data cache. If the cache has become corrupted, you might need to clear it for the app to work properly again. Unfortunately, the only way to clear an iPhone app's cache is to uninstall the app and then reinstall it from the App Store. But you can clear the McDonald's app's cache on Android without removing the app:

1. Start the Settings app and tap Apps.

2. If necessary, tap See all apps and then tap McDonald's.

3. Tap Storage & cache. 

4. Tap Clear storage.

Restart your phone

If you're still having trouble with the McDonald's app, you might want to restart your phone. This will flush out any temporary software issues that are plaguing the app and your phone. You can turn off most Android phones by holding the power button for several seconds, or you can swipe down from the top of the screen to see the shortcuts panel and tap the power icon. If you have an iPhone, here's how to restart it regardless of which iPhone model you own.

Reinstall the McDonald's app

If all else fails, you should delete and then reinstall the McDonald's app. This can not only clear out any corrupted data associated with the app, but it might solve a problem with the app installation itself. As a reminder, here is how to uninstall an app on an iPhone, and here's what you need to know to uninstall apps on Android.
