What is the mobile version option for?
When publishing your virtual tour, you can choose between different formats and versions that you wish to export. By selecting the mobile version option, the panoramas will be optimized to run on mobile devices. The downloading times for this version will be shorter while maintaining an optimum quality level for mobile devices. Since you will be creating two versions (web and mobile), you will need more space on your hard drive or server for storing the virtual tour. Still, it usually makes sense to create both versions (web and mobile) in order to make sure that clients entering with mobile devices are saving time and bandwidth.
