Im having several 360 degrees pictures in the 360 virtual tour.
When viewing on pc (chrome), there is no problem. All scenes are shown.
but when viewing op mobile phone (android and also Chrome) or tablet (android and also Chrome) some 360 pictures just wont show.
I can move around though, but in a totally black scene. Tried uploading the picture again, but no effect.
It's not that the picture is too large. Other 360 pictures with more mb show up fine.
What to do?
