I am getting the following error when loading the viewer on Safari browsers, both mobile and desktop: "Failed to load resource: the server responded with a status of 404 () https://buildreadyapp.com/viewers/blob:https://buildreadyapp.com/lmvworker.min.js.map" (buildreadyapp is my domain. The viewer file itself is at buildreadyapp.com/viewers/qr_viewer.php)
The error does not show on other browsers. Not sure what the problem is.
UPDATE: I believe this issue got resolved when I upped the memory limit for the viewer. This other post is related to the same problem. Before I increased the limit, the viewer would get stuck in an infinite 404 error loop and would not load. Now it appears to be working.
