Facebook launched Facebook SDK v8.0 on September 8, 2020, and wants advertisers to update this version as soon as possible to use the latest features (although the update is not a requirement for running ads on IOS 14.0). This version provides developers advertiser_tracking_enabled flag to limit how Facebook might use data that companies choose to share with Facebook, such as a user who can choose not to be tracked by ads. In addition, this update supports Apple's SKAdNetwork API. Please note that Facebook is currently unable to attribute app downloads through this SDK.

Advertisers who have a Facebook SDK and use automatic or manual premium matching need to be updated to Facebook SDK v8.0 to use personally identifiable information (PII) matching for IOS14 users, otherwise advanced matching will not work properly.

1) IGTV's high-frequency uploaders (more than 50 video users have uploaded to IGTV since 2020), who can now stream ads directly to their IGTV channels or videos.

2) YouTube high-frequency users (who have spent at least 50K on ads streaming to YouTube so far in 2020) can be directed directly to IGTV long videos without leaving the Instagram app.
