Hi Dave, Thank you for posting your concern. Allow me to provide support to your concern.
1. Has the spec of this api changed recently? 2. Concretely, what is "request", "operation" in the error message? For these 2 questions, it appears that the behavior that you encountered is related to this blog post that the maximum number of user_identifers set in a UserData object will be reduced from 100,000 to 20. This is to clarify that each set should represent a single user. 3. How handle the process when 20M userId list? As for this question, you will need to create multiple operations for each unique or single user to upload it in a user list. Also, allow me to raise a feature request to my team so that the update mentioned in the blog post will be reflected in our document, subject for review. For now, please follow our blog to get updated with news and releases about Google Ads API.
