Fix Facebook Login Errors & Login Loops

If you are unable to log in to Langmate using your Facebook account, or if you are stuck in a login loop, this is likely due to iOS App Tracking Transparency policies and your device’s tracking settings.

To resolve this login loop and successfully connect your Facebook account, please follow the step-by-step instructions below.

Steps to Fix the Facebook Login Loop

1. Enable App Tracking Permissions on iOS
   Adjust your settings based on your current iOS version:
   • For iOS 14.0 and later: Go to your device’s Settings > Privacy & Security > Tracking. Ensure the toggles for both Langmate and Facebook are turned ON (Green).
   • For iOS versions older than 14.0: Go to your device’s Settings > Privacy > Advertising, and tap Reset Advertising Identifier.
2. Uninstall the Facebook App
   Temporarily delete the Facebook app from your device.
3. Log out from Facebook on your Browsers
   Open your web browsers (such as Safari and Chrome), search for “Facebook”, and make sure you are completely logged out of your account on all browsers.
4. Restart your Device
   Turn your phone completely off and then turn it back on.
5. Try Logging into Langmate
   Open the Langmate app and tap Log in with Facebook.
6. If the Account Doesn’t Connect (Final Step)
   If you still cannot log in at Step 5, it means Facebook has not yet granted access. In this case, fully close (force quit) the Langmate app. Open Langmate again and try tapping Log in with Facebook one more time.

If you have followed all these steps and still cannot log in, please try using an alternative login method (such as Apple ID or Phone Number), or contact our support team for further assistance.
