A Realtor told me that in a iGUIDE vs Matterport comparison, Matterport wins because the iGUIDE Viewer is only in English and therefore people outside English speaking countries do not understand what is written.
Things like Main floor, Second Floor, Basement, Photos, Details Page are quick to be translated.
So I would like to suggest to consider finding a solution to add maybe a translation plugin with country flag to select language of the the Viewer.
Not for Stitch and not for the Operators and backend/ - not now at least - maybe one day. but for the visitors… only the Viewer - just to translate the important things.
