New Surface 3, also new to Windows 8.1. Was using the Facebook App, and clicked on a notification that showed up at the top right in the app. It gave me a choice of how to open it, and I chose the wrong option. So now when I tap on a notification, it takes me to Chrome, rather than opening it up within the FB app itself. I went to Control Panel...Default Programs... but can't identify the specific file type or protocol that controls this function. I assume it's somewhere there, as I can't find any FB setting that seems to address this. Anybody know how I can change this default, and have FB notifications open up in the FB app, rather than Chrome? Thanks.
