How can we host a JSON file at the site root so that our app works with universal links?

Hello,

There’s really no way to add a file into the root directory as Corvid “sandboxes” the site and its directories.

You should find out if there is any other way to do this since not all environments allow access to the root directory.

Try to check out related forum post here to see if it can help.

This is such a basic feature and should be allowed. By denying this feature, the wix website is basically useless for any team who also has an app which supports notifications.
