Firebase attribution tracking
I added a few networks for attribution tracking in Attribution->Network Settings and added those network SDKs, but how can I see conversions from specific ad network from Firebase? For example first_open.
If I go to Attribution-> click first_open -> and then trying to apply filter, there is nothing under Source. I suppose there should be my networks, aren't they? How can I see number of installs from specific ad network on Firebase?
It sounds like you're doing everything correctly -- although you shouldn't even need to apply a filter. At the bottom of the page will be a breakdown of the first_open conversions by source. This, for example, is what you'll see if you look at the Firebase Demo Project at the bottom of the first_open report:
If you're not seeing any data, my recommendation might be to wait a little while; sometimes it takes a bit of time for these reports to follow through. Also, I'm fairly sure these reports aren't retroactive. Once you add a network, you'll see attribution data for those networks moving forward.
