If you recently added the ability to log app events through the SDK, people will need to upgrade to a version of your app that contains this updated code. As people upgrade to the latest version of your app, your app event data in Facebook Analytics will begin to match your internal figures.
One way to validate the data is to only look at internal data coming from people who have upgraded to versions of your app that send App events. You should also verify that you're not conditionally sending app events—this will result in an incomplete count.
If you're using a mobile measurement partner (MMP), ask them to verify your app events integration.
If you're using both an MMP and the Facebook SDK to log app events, this can result in double-counting.
Verify that app events are being logged at the right time in your app. For example, if you're comparing purchase events, make sure that the purchase event is being logged when you're confident the purchase event has actually occurred—as opposed to the point at which a person clicks on a "purchase" button.
Some common causes for inaccurate totals or values per event are:
To view analytics for only your Messenger bot, create a new filter, then customize it in Facebook Analytics on the web:
Note: Not all roles can save filters. Even if you can't save the filter you created, you can still share it.
The Facebook Analytics email report gives you a quick overview helping you see highlights of your app activity and better understand the people using your app. Email frequency may vary between weekly and monthly, as we're testing the benefits of each option.
To unsubscribe from email reports, click unsubscribe here at the bottom of the email, and change your preferences under Developer Updates.
Alternatively, you can access your email controls directly from your developer settings.

If you're using version 3.19.0 or earlier of the Facebook SDK for Android, there's an issue with counting all app installs.
To avoid this problem, we recommend that you upgrade to the latest version of the Facebook SDK for Android. Use this guide to get started quickly.
Note: This issue doesn't affect measurement of any Facebook ad campaigns you might be running, but it does affect app install metrics in Facebook Analytics.
