AppsFlyer Events Started Failing with 'Appsflyer ID not set'

Hi Christopher,

Thanks for reaching out! I’m happy to help.

I reviewed your account and found that your AppsFlyer integration isn’t working because you haven’t set the $appsflyerId customer attribute for your app users. This required attribute is essential—omitting it will prevent the integration from functioning.
 
For more detailed guidance, you can refer to our documentation on AppsFlyer integration here: AppsFlyer Integration.
 
Hope this helps, Let me know if you need help with anything else.
 
Best,
