PSA: Enabling 5 Protected Audience and Fenced Frame features in Mode A/B

Five Protected Audience (PA) and Fenced Frames (FF) features were shipped earlier this year but not enabled in the Chrome-facilitated testing Modes A and B to prevent disrupting experiments and measurements during the Chrome-facilitated testing period:

• PA Real Time Reporting ( I2S )

• PA multi-bid support ( I2S )

• PA deprectedReplaceInURN via auction config ( I2S )

• PA multiple bidding contexts optimization (not web visible)

• FF allow cross-origin subframes to send reportEvent() beacons ( I2S )

With the end of the Chrome-facilitated testing period, we’re going to enable these features in Modes A and B to provide a more consistent developer experience and decrease the need for feature detection.
