Issue with StorageAccess API in Edge browser

[carac]

We recently noticed an issue with Edge Browser. We use StorageAccessAPI's to read cookie info from the iframe(tool) loaded in the Canvas. Recently this API's stopped working as expected. After granting the access, I still see the settings are not reflected, when I test access from the Iframe. Where as I see the access being granted on the main site. No issue with firefox. Anyone else seeing similar issue?

Due to problems with cookies we've moved all our locally developed tools to be single page application that make fetch() calls to the backend adding authorization headers in JavaScript code.

I know that's probably not a good fix but it seems to be a reasonable long term solution.

Alternatively have you tried using CHIPS, while this isn't supported in other browsers it should work in Chrome/Edge.
