Okay I managed to establish an AAC connection by unpairing and then repairing the devices. But this time I initiated the connection from the iPhone side, which seemed to solve the problem. "AAC" is still not a selectable option in the N3Pro's Bluetooth menu. You can only tell you're on it...

Has anyone else managed to stream in AAC from an iOS device? It's not showing up as an option in the Bluetooth menu. I'm only getting SBC from my iPhone X. I was hoping I could offload my BTR5 after getting this.
