Recently, when I set the SDK Target to 33, the AD-ID value of some users who probably have high Android is 00000000-0000-0000-0000-000000000.
In fact, the process of receiving gifts for the first registration is disrupted and the user can register and receive gifts multiple times.
Some write that we need to specify in the Google Play console that we want to receive ads and enable the option.
Well, maybe some, like me, have not published this application on Google Play. This is not because Google does not want to provide its ads to applications that are not published in its own market.
Some say that if the user has disabled ad personalization in Gmail connected to their phone, the value will be 0. I tested this and it was not the case.
Some say that if Google Play is not available, the value will be 0.

Of course, the necessary access has been added to the manifest.

B4X:

AddPermission(com.google.android.gms.permission.AD_ID)

What is the solution in the end?
Why doesn't Android give its developers a unique device identifier?
We've been struggling with a unique identifier for 9 years...

If the user deletes the advertising id in Android settings, it will be all zeros. If you're not publishing the app on Google Play, then you can create your own unique id.

What they mean is that with App Set ID we can create a unique ID for the user's device and then it will provide it to us as an Advertising ID?
So is this possible in b4a?

If you're in control of how the ID is sent you could just make up your own unique id.

In most cases the android_id is the best identifier: https://www.b4x.com/android/forum/threads/get-unique-id-for-user.124396/#content

I didn't understand what you meant by this sentence.

From what you wrote in your OP it seems that you're not using the ad id for ads. You refer to "registering & receiving gifts" - so where are those gifts coming from? I assumed (possibly incorrectly) that they were coming from you, in which case you would be receiving & logging the ad id for that purpose. If that's the case, then you could use any unique id for this - so you could use the Android id instead.
