Apple Search Ads attribution data request returns 404 after releasing app version built with Xcode 15.3

Greetings,

We're using MMP attribution (AppsFlyer), and also track attribution via https://api-adservices.apple.com/api/v1/ manually.

After releasing a new app version with the latest Xcode 15.3 / iOS 17.4 (the previous store version was built with the older software), our Apple Search Attribution in MMP statistics got worse. In out error log we can see that https://api-adservices.apple.com/api/v1/ returns 404, although we're calling API in 5 min after token is retrieved. Are there any issues observed with Apple Search Ads attribution on iOS 17.4?

Thanks
