Hi,
Thank you for contacting the Mobile Ads SDK Support team.
When testing, ensure that you have the Facebook app installed on the test device and be logged in with a valid Facebook login. See Meta's documentation for more details. Without this, it is expected that Facebook might not bid (though they still might get bid requests).
I checked the sample project with the provided IDs and am able to reproduce the issue when a single ad source test of the ad inspector is enabled for Meta Audience Network (Bidding).
As per our observations ads are not returning from third party resources (Meta Audience Network).
This happens due to below reasons:
Kindly refer to your third-party ad source to understand why the ad source may not be bidding.
Also refer to this link for more information related to troubleshooting the bidding issue.
Please reach out to us, if you need any further assistance.
