I’m not the developer, but I do also write app backends for a living so I know there is some nuance that you’re skipping over in your response. But if you have a way to do this completely anonymous on android I’d suggest offering help to the developer who made this.

Something that… links it to the device? Like, a unique ID that Apple can identify?

APNS tokens are linked to the app install and renew on a certain timeline. Already making them not exactly the same as a device identifier.

Edited for further clarification. It’s not about Google, it’s about what Android needs to receive notifications: https://www.iceblock.app/android

Apple notification identifiers are unique to an app install and regularly change though, so it’s hardly a device identifier.

And the developer needs a device ID for that. Which is their objection: https://www.iceblock.app/android

Thanks, but I’m not the developer of the app so that’s not really relevant for me.

This is IOS only owing to Android play store collecting a device identifier; the creator wanted complete anonymity

Quote from some other place people were discussing it. Unfortunately no source on it.

Don’t threaten me with a good time
