Hello:
First let me start by saying I am not a programmer or developer, however it's costing me a small fortune to try and fix this issue with no success. From what I have been told, the tours are uploaded as equirectangular images and Krpano converts the images to cubic for the HTML5 iPhone/iPad interface. When the image loads on the iPhone/iPad the tour image is really zoomed in. I know there's commands in the regular code to make changes to the resolution but is there a similar code to make this change in the HTML5 version.
Here's a sample link to try on your iPhone/iPad https://krpano.com/forum/wbb/undefined
