title: Filter signed in user in Firebase Analytics Dashboard
body: <p>Firebase analytics dashboard offers teh posibility of filter by signed in users. I added the sign_up event to my app and I already have activity for this kind event. Unfortunelly, when I use the filter, there is not information. What do I have to do tell to Firebase that the user is signed id and use the filter.</p>
