Yes. In order to access BillPay and eStatements, you need to allow “pop-ups” from Trailhead. Many web browsers (such as Internet Explorer or Firefox) have tools to turn on or off text windows called “Pop-ups”. When visiting unfamiliar web pages, it is precautionary to block these pop-up windows as they could be used to display annoying ads or possibly impose a security risk. However, BillPay and eStatements will not work if pop-up blockers are turned on for Trailhead.
