If you were one of the 87 million users that might have been affected by the social media platform’s recent Cambridge Analytica privacy breach, then you will be getting a detailed message in your news feed starting Monday.

In the wake of the scandal, Facebook said that users who may have had their data shared with Cambridge Analytica will be getting messages this week, according to the Associated Press. In addition, in an effort to do some damage control, all Facebook users will be receiving a notice with a link to see what apps they use and what information they have shared with those apps. They will be given the option to shut off these apps or completely turn off access to third-party apps.

The ongoing Cambridge Analytica scandal has been a thorn in Mark Zuckerberg and Facebook’s side. In March, it was reported that Cambridge Analytica, the data firm backed by Donald Trump supporter Robert Mercer and once steered by former Trump advisor Steve Bannon, obtained personal information from 50 million Facebook users without permission. That data then was used to target voters and influence the 2016 election. Of those affected, Facebook said more than 70 of the 87 million users are in the U.S. with over a million each in the Philippines, Indonesia, and the U.K.

Zuckerberg has since acknowledged that this has been a “huge mistake”. He is set to testify before a joint session of the Senate Judiciary and Commerce Committees on April 10, then appear the next day before the House Energy and Commerce Committee, answering growing questions about data privacy and how Facebook plans to address the problem.
