1. Why does our DAU data differ from the data in User Report on the platform?
It might because AdTiming applies GAID for the statistics of DAU.
2. How do you get stats on performance from the other networks?
We ask for API keys from each network you integrate, and use those to gather impressions, clicks, installs, and revenue. We also track impressions and clicks on our own. You can find these in the dashboard under the mediation tab.
