Help – Meta Ads Events firing in SDK / Events Manager but 0 results in Ads Manager (App Promotion)
Posted by on January 18, 2026 at 9:17 amHi everyone,
I’m seeking some technical insight on an gap I’m seeing with a new Meta App Promotion campaign.
The Context:
- Campaign Objective: App Promotion (Optimizing for 'Complete Registration').
- Platform: Android (separate ad sets).
- Timeline: Campaign has been live for ~24 hours, spending full daily budget.
The Problem:
My Events Manager shows healthy activity (995+ 'Activate App' and 77+ 'Complete Registration' events received in the last 24 hours). I am seeing a clear lift in my backend registrations from the targeted geos.However, Ads Manager is reporting 0 conversions for complete registration.
What I’ve checked so far:
- Event Mapping: The optimization event in the Ad Set level is definitely mapped to the 'Complete Registration' standard event firing in the SDK.
- Account Health: "Data Source" health tab shows "No active issues" (Green light).
My Questions:
- If the events are showing up in the Events Manager/SDK tab, does that mean my technical setup is definitely correct?
- Is there usually a long delay (longer than 24 hours) for app events to attribute to a specific campaign in Ads Manager?
Any insight would be huge!

Quite a short time for one but on the ad level in the tracking section, is the app enabled there as an event? You cannot attribute without it.

App events can take 24-72 hours to fully attribute in Ads Manager even when firing correctly in Events Manager because of Meta’s Aggregated Event Measurement (AEM) delays for mobile… check your attribution window settings match between Events Manager and campaign setup (default 7-day click), and verify Event Match Quality isn’t flagged as “poor” which causes Meta to reject conversions even though they’re firing in the SDK, because 24 hours is too early to panic but after 72 hours with zero attribution then the mapping is broken not event firing.
