The 3DVista app crashes when starting it on my Quest device. Why is that?

If the 3DVista app on the Meta Quest device shuts down immediately after opening, it is necessary to utilize a different Facebook/Meta account on the device facing difficulties. This is because there is a restriction imposed by Meta on the number of headsets that can use the app with the same Facebook/Meta account.

Furthermore, certain users have found that clearing the app data, which can be done in the Settings > Storage menu, can help overcome this problem.

Finally, make sure that your tours still maintain the HTML files with their original name, that is "index.html" or "index.htm". These files should not be renamed.
