@Shashi Shailaj Nope, after working through with support they've unlocked DSv3 series for me. but the D series (as well as every other series) is still marked unavailable, even though it shows I have 10 quota available. I've even tried working through with support to see is somebody could clarify for me why this is happening; but they failed to even communicate what they did to identify and correct the DSv3 series for me. Microsoft definitely seems to have some hidden controls, and it's quite frustrating. What's the point of having the quotas screen, if it's not representative of what you can actually do?
