If you're reading this box, JavaScript isn't running — this app is built entirely in JavaScript, so nothing else can load.
Almost always it's the app you opened the file in, not the file. Try one of these:
- Download the file first, then open it in Chrome (Android) or Safari (iPhone) rather than a preview window.
- iPhone: save to Files, tap the file, then tap the share icon and choose Open in Safari.
- Android: save to Downloads, then open Chrome, type content:// in the address bar, or use a file manager and choose Open with → Chrome.
- Most reliable: drag the file onto app.netlify.com/drop and open the link it gives you. Works on every device.
