“Tracking is broken even if performance is not right... if you look at the itunes dashboards you're like you think all right you know you didn't just go crashing down which is what i was afraid would happen right right that has not happened.”

Tracking Is Broken — But Performance May Not Be. Check Blended Numbers Before Panicking

After ATT launched, reported CPAs from Facebook skyrocketed because the privacy threshold hid attribution — but many apps' iTunes dashboards showed stable or growing trial numbers.

Before cutting iOS spend, check blended acquisition cost (total spend / total trials) against the App Store revenue dashboard to see if real performance actually degraded.
