Added QA/Test-All-Platforms after discussing the above with @LaurenWags. We should check/ensure the above is working on all platforms as we want to ensure that deep linking is working as expected.

The above requires 1.75.165 or higher for 1.75.x verification 👍

After talking to @tmancey, I removed the feature/ads label as this is not an ads issue.
