Greetings. We would like to extend the Privacy Sandbox Ads APIs experiment for all APIs contained in the unified origin trial including: Topics, FLEDGE, Fenced Frames, Attribution Reporting, and Shared Storage.
We are sending a single intent for the extension because the rationale is shared among each of the APIs. Functionally, we are still asking for approval to extend each of the four API's experiments independently.

Unified OT Thread:
Goals for experimentation
We'd like to extend the origin trial for 3 additional milestones, with the extension starting in 108 continuing through Chrome 110. The initial experiment is running from Chrome 101 through 107.
Any risks when the experiment finishes?
None. The unified origin trial is only available for a subset of users requiring participants to perform feature detection to use the APIs.
Reason this experiment is being extended
We plan to address several points of feedback raised in the next several milestones, and give the ecosystem more time in stable channels to continue their experiments.. As a result, this will give developers the opportunity to perform extensive testing on higher traffic (within traditional experiment guidance).
We are requesting this change well in advance of the initial end date to make it clear we intend to support meaningful testing within Chrome Stable, and plan to release a number of improvements and bug fixes for the APIs over the next few milestones. These improvements include, but are not limited to, the following:
