We've reached our milestone for the ~35% ramp-up and intend to continue heading towards ~50% from Wednesday, 23rd August.
As before, users need to relaunch Chrome before version updates or incremental API updates take effect. This ramp up includes a mix of different experimental groups. The main group will have all APIs enabled, but we are also running isolated groups with individual APIs enabled to allow for easier detection of any potential issues. The planned traffic levels for this phase of the ramp up are as follows:
Attribution Reporting: 50%
Protected Audience: 50%
Shared Storage: 50%
Fenced Frames: 55%
Topics: 50%
Private Aggregation: 55%
