I am trying to add an announcement section to every site/sub site in our site collection. It will be the same announcement page so everyone sees the same announcements. I can go to the site where I made the announcements (our home page) and edit page > insert web part and the announcement list is there, but when I go to a sub site or other site within the collection, it is not in the web parts. I can make web pages and all the home page web apps are there including my announcement list.
I have exported the web part and imported it into the web parts gallery and it is there but it does not work. I have also used designer to do it (instructions at link). https://www.youtube.com/watch?v=TntwRm78b_4 This video is of SharePoint 2010 and I have 2013. Does anyone know how to do this?
