Starting in October 2020, in order to further ensure the safety of BM users, Facebook will require all BM users to complete two-factor authentication at the next time to ensure the security of platform use. Facebook believes two-factor authentication prevents advertiser account information from being compromised and unauthorized users from inglying on to BM.

Users associated with BM are required to perform two-step verification. Users who have not completed two-step verification after a certain period of time will not be able to continue to use the BM feature, please partners to assist the relevant personnel to complete the verification as soon as possible. To get people used to the new policy as quickly as possible, Facebook will periodically send reminders and in-product notifications. BM managers can also confirm the verification status of all associated users through BM, with a red logo next to the names of users who have not completed two-step verification.

Starting October 12, click attribution analysis for some customers will become the default 7-day statistics window, and you will no longer be able to get 28 days of results from ad administrators and ad reports. This change only affects reporting and has no impact on ad delivery or ad performance.

Increasing restrictions on bit privacy are being set on different browsers, which will affect the ability of enterprises to measure user behavior/communication across domains and devices. While the seven-day statistical window could lead to less-return conversions, Facebook believes the change will help companies better measure marketing investments in such an environment.

On October 12, 2020 (before the test takes effect), advertisers can:

1. Use the comparison time window to see the different conversion results from different statistical time windows

2. Download the 28-day statistical time window report in advance

3. Update any automatic rules that currently use the 28-day statistical time window to avoid any unexpected adjustments in spending when this test takes effect.

Advertisers who require a 28-day attribution backtracking report can now go to the Ads Insights API to download the 28-day report until the browser restrictions take effect next year.

Users can now choose to communicate with their contacts across platforms (Messenger, Instagram) while maintaining control over privacy levels, report quality, and blocking. This feature update reflects Facebook's vision for a "private social platform." Enterprise accounts can choose to update to this new feature, but can only reply and forward, can not actively send information across platforms. This update does not affect existing enterprise messaging tools such as Unified Inbox, Pages Inbox, or Messaging APIs. This feature is gradually opening up to more regions. Facebook wants people to be able to easily contact friends and family using any service they offer.

As before, Facebook recommends that users update to Facebook SDK v8.0 as soon as possible to use the latest features. This update supports Apple's SKAdNetwork API. 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.

Facebook's support for Instagram video ads, plus videos or channels directly linked to IGTV, began on September 24th. This update will help:

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

2) Youtube high-frequency users (who have spent at least 50K on ads since 2020 are streaming to Youtube) can be directed directly by ads to watch long IGTV videos without leaving the IG app.

Starting in October 2019, Facebook began removing 6% of its ad accounts for "regional targeting" when creating "lookalike audience" ads. By October 5, 2020, that number had increased by 10%, but only for new and edited campaigns.

The developer did not receive regular communication about the Marketing API v6.0 deactivation, so the SDK deactivation was delayed. Facebook has fixed a secondary technical issue to prevent it from happening again.
