On August 10th, there was a noticeable decrease in ATT reported installs attributed to Facebook, dropping from an average of 70 installs to merely 15 installs per day.
By August 25th, another decline was observed in reported SKAN installs on Facebook. This was accompanied by an increase in CPIs and a rise in the ratio of non-attributed installs on AppsFlyer. Interestingly, when looking at the blended numbers, there was no significant change, and there was also no surge in organic traffic as per App Store Connect data.
Fast forward to October 14th, there was a campaign relaunch with the Singular MMP. This move saw a boost in SKAN reported installs and a commendable drop in CPIs from $22 down to $11. However, these numbers still weren't at the desired benchmark of approximately $5. Despite increasing the budget, the ATT installs did not see any increase, hovering consistently between 15-20 daily installs.
That is the situation overview. As far as the tech goes we have RevenueCat integration with identifier collection, an MMP integration (previously AppsFlyer, now Singular). We request the ATT prompt after signup. Obviously this involves different integrations but RC is connected to all of them too and we are trying to find the cause for this in all areas, so maybe someone here has struggled with something similar or knows ways to troubleshoot this.
