Twitter Ads API partners and developers:
We have been working diligently to resolve issues delaying processing of uploaded tailored audience lists and are starting to see the backlog clear. If your audiences were uploaded more than a week ago and are still being processed, please re-upload your lists. Note that processing can typically take up to 24 to 48 hours.
We apologize for the inconvenience this may have caused.
