Facebook Ads - iOS

Please provide the following:

  1. SDK Version: 40.0.0
  2. Platforms(Android/iOS/web/all): iOS
  3. Add the appropriate “Tag” based on what Expo library you have a question on.

I’m trying to get Facebook ads working on an iOS device. I have access to an Android device, and an iOS device. The problem is ads do not appear on iOS 14.4, but do work on the Android device.

I don’t believe this is an Expo SDK issue, but I’m just looking for help from anyone that has gotten ads to work on iOS. I downloaded an app to give my IDFA, which Facebook asks for to register a test device. The app returns all 0s, and I cannot find any setting in my phone that will enable this identifier. I tried entering my IDFV on the Facebook monetization page instead, and that has also not worked.
