I tried the second solution and it still redacts the device id
<Google> To get test ads on this device, set:
GADMobileAds.sharedInstance().requestConfiguration.testDeviceIdentifiers = [ "<private>" ]
I tried your second suggestion of using app for getting ad id, the IDFA it gives looks like this : 7AC7B1A6-20A3-4CA3-AEE5-644E9603C807
while Android gives some kind of hash like this:ABB0E32DE3F194183CACCB09D7ACB0E7
Anyway, when I pass the IDFA that these apps give as testDeviceIdentifiers it doesn’t work for iphone.
maybe I need to apply some hash on the IDFA ?
Can anybody who uses device to test Google UMP or admob tell me how he got the device test id for their iphone ?
