When we are looking at device ID data, we seem to have more than 2000 devices (android + iOS) in adobe audience manager, however, when we look at the android and iOS devices in our ad server, we are only seeing around 500 devices. Does anyone know why that is the case? Is it due to misconfiguration of APP SDK or is that how the traffic is? We even have device co-op implemented and that doesn't seem to scale either. Any help is appreciated.
