WD Blue m.2 SATA not working with Asus 970 Pro Gaming/Aura

I have a WD Blue NAND SATA SSD m.2 2280. (WDS100T2B0B)

Current MOBO: Asus 970 Pro Gaming/Aura with m.2 NVMe slot PCIe x4

Drive has both b+m key slots and fits and seats just fine. What am I doing wrong? Does this drive fit but isn’t compatible? I thought it was compatible with all m.2 slots.
