Apologies for the confusion @msomm ! I accidentally misread the inquiry as being about the wrong endpoint.
To address your query regarding the TON upload endpoint: Membership requests are ADD/REMOVE/DELETE calls to the POST tailored_audience_changes endpoint. Therefore, only this section of the previous response is applicable.
the last update field, this field should be updated each time the audience size estimate has been updated, which generally takes a few days AFTER the membership request has been received. We do not have a timeline available to enable the Real Time endpoints for GA, and we will be sure to update everyone with an announcement once we know more. We’re still trying to work through existing issues with the TON API.
Could you please let us know which specific Audiences and Ads account_id you’re referring to? We can investigate the issue further on our end just to rule out any other issues.

Please disregard the previous response, however, regarding your query about Tailored Audience changes, the following is applicable:
Once these records are processed, the final change to the Audience size may not be the sum of the existing size plus the newly added members, owing to the fact that members are only added to an audience once a sufficient confidence is reached, after de-duplication. Due to this, final audience sizes may not be equal to the total number of members added to the audience. I hope that helps!
To clarify, once we receive a call to the POST tailored_audience_changes endpoint, these changes are processed as per the methodology quoted, above.
Please let me know if there’s any further questions.
Thanks!
