Ok I'm pretty new to firebase and analytics but I'm seeing some kind of incongruency between what the dashboard is showing me and what the Audiences tab shows me.
Dashboard:
and the Audiences (predefined Audience All Users):
Any ideas if I'm looking at this the wrong way or if it's just a bug?
Thanks!!
The threshold of 10 is actually based on Advertising Identifiers (and not Analytics "users"). And so, if your set of 13 Monthly Active Users has fewer than 10 Advertising Identifiers among them (for example, if you just uninstalled/re-installed 13 times on one device), the report will still not meet the threshold requirements.
