To resolve the login issue you're experiencing with both the Arby's app and website, follow these step-by-step instructions:

1. Check Internet Connection: Ensure that your device is connected to a stable internet connection. You can try restarting your router or switching from Wi-Fi to mobile data.

2. Update the App: Make sure that the Arby's app is updated to the latest version. Go to the App Store, search for Arby's, and update if necessary.

3. Restart the App: Completely close the Arby's app by swiping it away from the app switcher, then reopen it. This can refresh the session and help resolve temporary glitches.

4. Clear Cache and Data (if applicable): If you're using an Android device, navigate to your device settings, go to Apps, find the Arby's app, and clear the cache. For iOS devices, uninstalling and reinstalling the app can serve a similar purpose as iPhone does not have a direct cache clear option.

5. Try a Different Browser: If the app still doesn't work, attempt to log in via a web browser. Switching to a different browser (e.g., Chrome, Safari) can sometimes overcome issues related to cookies or browser settings.

6. Disable VPNs or Proxies: If you are using a VPN or proxy, disable it and retry logging in. Such services can sometimes interfere with the app's ability to connect.

7. Check Server Status: There might be maintenance on the Arby's servers, which can temporarily prevent logins. You can check social media channels or websites like Downdetector to see if other users are experiencing similar issues.

8. Contact Support: If none of the above steps work, contact Arby's customer support for assistance. You can reach them through their Contact Us page - [learn more].

9. Visit Local Store: If the issue persists and you require immediate assistance regarding your account or orders, visit your local Arby's and speak to the manager about the login problems.

This multi-step approach should help you troubleshoot and potentially resolve the login issue with the Arby's app and website. If further problems persist, consider seeking assistance directly from Arby’s support. - [learn more]
