After every check, clear cookies and local storage in dev tools.

No popup.

With AdGuard mini all good

Reproduce the issue on the linked Billboard page with the provided scriptlet rule, clearing cookies and local storage between checks. Compare the iOS behavior with AdGuard mini; done means the subscription popup no longer loads and window.tp.offer is redefined as expected.
