We have a hosted web app for digital signage that we run 24/7 on fire tv devices. One functionality that we are having issues with is refreshing the page to fetch the latest version of our web app. We have tried using window.location.reload() and window.open(appUrl). Both of these functions work when testing the Web App Tester from Amazon, but when we deploy them to production they just result in a white screen. Does anyone have any ideas on how we can achieve this same functionality?
