Why does it say failed face tracking?

Hi lexcie67,

It would be our pleasure to assist.

Try to edit, duplicate, or delete and recreate your Memoji to see if you can use it in any other form. The "Manage your Memoji" section of Use Memoji on your iPhone or iPad Pro will explain how.

Manage your Memoji

Want to change a Memoji that you already created? You can edit the features, duplicate an existing Memoji with new features, or delete a Memoji.

1. Open Messages and tap the Compose button  to start a new message. Or go to an existing conversation.

2. Tap the Memoji button  or Memoji Stickers button , then select the Memoji that you want. 

3. Tap the More button . Then choose Edit, Duplicate, or Delete. 

If you want your Memoji on all of your compatible devices, you need two-factor authentication enabled for your Apple ID, and you need to be signed into iCloud with the same Apple ID on all the devices. You also need to have iCloud Drive turned on. Go to Settings > [Your Name] > iCloud > iCloud Drive.

This may refresh your Memoji and allow you to start using it. If you're still experiencing an error when you attempt to use your Memoji, reach out to Apple Support for additional options. They'll be the experts when it comes to errors like this.
