Since the introduction of zeroed out GAIDs is the same feature as Limit Ad Tracking and Limit Ad Tracking has been available on Android for years, we do not expect a sudden decrease in Attribution or heavily impact our Attribution reporting. This is primarily because Branch does not collect the GAID when Limit Ad Tracking is enabled by the end-user.
With that said, many Ad Networks are implementing alternative parameters and methodologies to provide accurate attribution reporting even with Limit Ad Tracking enabled. Please evaluate the matrix below.
