I still couldn’t find the cause, but I found a roundabout fix for anyone who has this problem in the future. Redirect/send the user to a new page and add the URL Redirector from the App Store. Set ‘URL (prefix)’ to a forward slash (/) and leave the rest of the information the same. Now carry on as you normally do in your app.
- There is also a settings.json where you need to put the slash in front of the css path
