Unity Ads not serving test ads to test device(s)

Hello!

My first (Unity Ads) supported game is ready for submission to iOS and I’m currently testing the final production build. But it’s showing real ads (rather than test ads) even though (as far as I am aware) everything is setup to show test ads correctly.

The following Unity Dashboard settings are configured…

Ad delivery status: Ad delivery enabled
Test mode: Client test mode not overridden

I’ve setup the three test devices (and triple checked their Ad Id’s)…

Device: This device is now serving Unity (Test Ads)

And on iOS the following settings are configured…

Personalised Ads: Enabled
Allow Apps to Request to Track: Enabled
Tracking: Enabled

But when testing on the iOS device, it’s showing real Unity Ads. This has happened twice now and given the advice on this forum, I’m reluctant to use the test flight (or the Android version) any further for fear of triggering another real ad and being blocked by the automated blocker!

Any help would be appreciated.

NOTE: The game is using Unity Ads 4.2.1

Update…

I double checked the iOS device IDFA using MyDeviceId by Apps Flyer. It confirms the IDFA matches the id entered into the Unity Ads Dashboard.

So as far as I can tell, everything is setup correctly.

Is anyone from Unity (or otherwise) able to help with this please?
