FAN ads always end up with the "No fill" error

[jkozlowicz]

MAX SDK Version

12.1.0

Device/Platform Info

iOS 15+

Current Behavior

Ads from Facebook Audience Network always end up with the "No fill" error despite the fact that everything seems to be configured properly.

I followed the official AppLovin guide for the integration and I can display ads from the AppLovin network, but when I force the ad to be loaded from FAN, it always fails. I have been also accepted by Facebook to the MAX Open Beta programme.

I have properly configured the interstitial ad in the Facebook Business Manager and I reference all the FB ad ids both in the swift code as well as in the MAX web UI. It shows that the integration is configured properly with a green checkmark. The on-device debugger also shows that everything is alright.

Expected Behavior

Ads from FAN are properly loaded and displayed.

How to Reproduce

• Create an interstitial FAN ad unit
• Plug in the ad into AppLoving
• Try to load the add on iOS 15+ with SwiftUI

Additional Info

Please take a look at the errors, a short snippet of source code, and a screenshot. I have checked all the integration guides multiple times and I cannot figure it out. I already have it live and users are only being shown ads from AppLovin network, because the FAN network are not loading, which is not optimal...

Thank you!

Facebook actually has a lot of requirements for their test mode to work. I've listed them out below:

• ATE flag needs to be set
  COPPA (ageRestrictedUser) and LDU needs to be false
• App needs to be live and installed from the App or Play Store
• Will only bid in California if CCPA is set
• Does not fill for new apps that are not on the latest version of the Facebook SDK
• App needs to be approved by Facebook
• You can also check the Facebook checklist for additional integration issues: https://developers.facebook.com/tools/property/checklist/
• or try VPNing to a state other than California

@thomasmso thank you for your reply.

Facebook actually has a lot of requirements for their test mode to work. I've listed them out below:

• ATE flag needs to be set
  ATE has been set according to this guide:
  https://developers.facebook.com/docs/audience-network/setting-up/platform-setup/ios/advertising-tracking-enabled/

with the following code:

// Set the flag as true
FBAdSettings.setAdvertiserTrackingEnabled(true)
// Set the flag as true
FBAdSettings.setAdvertiserTrackingEnabled(false)

COPPA (ageRestrictedUser) and LDU needs to be false
LDU is disabled with the following code upon every app launch:

import FBAudienceNetwork
⋮
FBAdSettings.setDataProcessingOptions([])

I couldn't find any reference to COPPA in the docs you linked so I cannot say whether it is true or not. Could you please point me to some docs that describe how to disable it?

• App needs to be live and installed from the App or Play Store
  It's been live for 2+ years and is available on the App Store.

• Does not fill for new apps that are not on the latest version of the Facebook SDK
  I think I am now 1 version behind, but it was the latest version when I worked on setting up the ads with AppLovin.

• App needs to be approved by Facebook
  The app is officially approved by Facebook. I have green checkmarks everywhere + users have been using Facebook Login in my app for a long time already.

• You can also check the Facebook checklist for additional integration issues: https://developers.facebook.com/tools/property/checklist/

This page is broken.

• or try VPNing to a state other than California
• Will only bid in California if CCPA is set
  California is definitely not my most important geographical region and I mostly have users from Europe.

Looks like I've already covered most of the points and the integration still doesn't work. Is there any other way to escalate this to get help? I've invested quite some time into setting it all up with AppLoving and I'd like it to work properly.

Thank you!

I just updated to 12.4.0 in order to provide the privacy info that Apple started to require since a few days ago and I noticed this log statement in Xcode. Perhaps you can see something that is off?

Hi @jkozlowicz, for Facebook's test mode to work, COPPA (Age Restricted User) needs to be set to false but the logs you shared show that it has not been set. You can set this using our API here

[jkozlowicz]

Hi @NanaAmoah,
thanks your reply. Indeed that was missing, but unfortunately the ads from FAN still do not load.

I get the same "No fill" error. I just set that flag to false, logged in into facebook, and tried to show ad with FAN, but it failed.

I am attaching a screenshot from the on device debugger. Could you please suggest more steps to try out in order to enable FAN?

Thank you!

@jkozlowicz I have exactly the same issue. Have you managed to resolve it?

[jkozlowicz]

@maxvone sadly, I haven't. I've plugged in everything according to the official guides from MAX and FAN, but still only ads from MAX are being served :/
