AppLovin SKAdNetwork itunesitem must match advertised bid.bundle.
AppLovin SKAdNetwork itunesitem must match advertised bid.bundle.
What it means
AppLovin SKAdNetwork itunesitem must match advertised bid.bundle. This check applies to the selected vendor contract and integration direction.
Why it matters
The declared profile checks the published partner contract alongside canonical OpenRTB. It does not verify runtime approval or account configuration.
How to fix it
Use an option offered by the matching request. Check the request and response together at the reported path.
