Seems like Krpano doesn't work with the Oculus Go browser.
Using version 6.0.14.163136196 from 18.07.2019.
It works fine in desktop 2D mode, but entering VR mode it only shows image in the left eye and is misaligned. So left eye can see parts of both the left and right part of the image.
Klaus please investigate ASAP!
I tested with examples on Krpano.com.
