Hi there! I'm sorry to hear you're having trouble with age verification on the Yoti app. Let's try to work this out together.

Firstly, it would be helpful to check a few things:

1. Check Personal Details: Ensure that all your personal details like name, date of birth, and address are correctly entered in the Yoti app. Any discrepancies might cause verification failures5.

2. Document Quality: Make sure the document you are using for verification is valid, not expired, and clearly readable. Sometimes, the issue could be due to a poor-quality image capture.

3. Network Connection: Verify that you have a stable internet connection. Sometimes network instability can cause verification processes to fail.

4. App Updates: Ensure that your Yoti app is up to date. Outdated app versions might have bugs that could lead to such issues.

If you've checked these and the problem persists, you might want to consult the Yoti support page for common error codes and solutions or reach out to their customer support for further guidance1 9.

If none of these steps work, it could be something specific to your account or situation. Yoti's customer support might be the best route to take at this point. You can contact them via their support page3.

Let me know if this helps or if there's anything else I can do for you!
