More info on how an iOS app can leak device ID? I thought Apple did away with access to device IDs and only provides a per-developer ID.

It’s in the Apple app store App Privacy disclosure [1]

Location (“coarse location”), identifiers (“device id, user id”)

^ both are deemed a necessity for app functionality, with deviceID required for analytics too.

The "device ID" part is probably false and a red herring. What actually matters is that google can correlate which challenges a given device is solving, so if it's solving 10k challenges per day, it can be marked as being suspicious.
