Setting up the Meta Audience Network ad source failed

Hi all,
I have followed the guide of Setting up the Meta Audience Network ad source Unity Documentation.
However, I got the failed status. See the below image


Hope someone can help me to solve this problem. Thank you so much!

Thanks for reaching out, it seems the API access has been deactivated on the Meta side. Meta has a Data Use Checkup process you will need to go through which may be related. If this isn’t done Meta will disable access to their APIs for the app. This is the documentation about it: Data Use Checkup - Meta App Development - Documentation - Meta for Developers

Thank you for your help! I have reactive my Meta app and set ad source successfully

Wonderful glad to hear this solved this issue. Thanks for reaching out!
