On 2016-09-01 02:00 UTC, we identified an issue with the
POST accounts/:account_id/tweet endpoint when using the
video_id param in combination with video media uploaded by another user.
This only impacts videos that are uploaded using the
POST media/upload endpoint when the
additional_owners parameter is set and only when one of the other owners tries to use that video when creating a promoted-only tweet.
Please note that our teams are engaged and working toward resolving this as soon as possible.
We will follow up once this is resolved. We apologize for any issues this may have caused.
