ATT approved = terrible match rates

[Romain Bitard]

Hello,

I have terrible match rates for users that accepted ATT (cf. att.png). 

Do you know what causes that ? What can I do to improve it ? How can I diagnose this problem ? 

Thanks in advance for any help you can provide

For context I use unity and the default "iOS 14 Advertising Support" package

I update admob sdk and adapters regularly 

Cordially,

Romain
