As relatively new to this performance marketing/app ecosystem world, like many others trying to wrap my head around ATT.
We spend minimal on ads, (primarily FB/IG), and we already have an LAT rate of 25%, so aside from inability to retarget or attribute, wondering what we lose with not showing prompt - especially if opt-in rate going to be low anyway. Most conversion events happen on day 0. We then just rely on SKAdnetwork. Perhaps this is just due to my lack of understanding.
