I have created a basic instant app using a map made by another member of my organization. I successfully embedded the HTML into our WIX website. Two days ago, I had no trouble viewing the map-app both directly from the arcgis website and in my WIX website. As of now, the app will not load at all from either the WIX or arcgis websites (completely blank white page) in Safari, but it does still load in Chrome and Firefox. I have updated my computer and tried closing and reopening Safari many times. I also tried making a new app from the same source material, as well as messing with nearly every setting within the instant app options. None of these solutions worked. For now, I just put a disclaimer on the website saying that the map is only visible on certain browsers, but I am very frustrated that it was working and now it isn't. Please let me know if there is anything I can do to fix this.
Here is the link to my app: https://www.arcgis.com/apps/instant/basic/index.html?appid=a07d4ae404bc46b88ec5c38391ed1797
Thank you!
