Geospatial pre-release - iPad Air (4th gen)

Do I have the right system requirements?

I created the geosptial experience on mac, and then used my ipad Air (4th generation) to scan QR code, and it properly prompted me to turn on location on my ipad , which I did. 

But then it still said unknown location (see screenshots labeled "Dino") and it wouldn't load the geospatial experience on the ipad that I am using.

In the unknown location detected, I saw animation to wave my device around, and I tried that. But didn't solve problem. I even took few steps forward and re-scanned. It gave the same unknown location prompt.
