How to understand inconsistent behavior with AdServices API?

I'm trying to pull Ad Attribution data using the AdServices method of pulling an attribution token and using it against the "https://api-adservices.apple.com/api/v1/" REST API.

The App Tracking Transparency is not setup because I do not want to pull the device's IDFA. I simply want to record search ad conversions on the app's first open.

This was working up until today on my iPhone and iPad however it stopped working today. I was able to pull the data once successfully from the iPad but that has been it.

I now receive an "Error posting to Attribution server" error pulling the token and if that succeeds, I then get a "The app is not authorized for ad tracking" error.

Nothing has changed in the app's code so I would like to better understand what is wrong?

Any success with this? We're doing the same thing, just trying to get ASA attribution data but are also receiving "The app is not authorized for ad tracking" error
