It's not far away at all, don't worry. Plus, Tinashe is in South America right now. She doesn't have the time to promote right now and they are probably releasing the music video pretty soon.
The gap between the release and the adds is perfect. They're making sure the song won't be frontloaded, cause urban (and to some extent rhythmic) tend to add songs and then never play them or play them twice and then drop them.
They're letting the song breathe past its early hype and maybe get pre-adds spins from big stations. I sense an AllAccess banner coming too. Don't let me down RCA
