Thanks again for bringing this to our attention, @1kon1k.
We have identified the following Promoted Tweets that you’re seeing in the UI (using the “All Tweets in campaigns” filter), but that aren’t being returned when making a request to the GET accounts/:account_id/promoted_tweets endpoint:
747520249767989248
769245047481073664
769249054807162880
769489726147469312
(Note: 769513828501557248 is not currently being promoted, so you should not expect to see it in the UI (using the filter mentioned) or via the API.)
In addition, it is not possible to see the campaigns or the line items that those Promoted Tweets are associated with. The affected campaign IDs are 5bks3 and 5t9qe; the affected line item IDs are 5jfnp and 62afr.
We think we have identified why there is a discrepancy, but wish to investigate further. We’ll update you once we know more. Thanks for your patience.
