Bluetooth Internet Note

Bluetooth internet may disconnect when your phone screen locks or the browser/app is moved to the background. Keep the connection page open in the foreground while using it. On iPhone, we recommend setting Settings → Display & Brightness → Auto-Lock to a longer duration.

Offline file upload is not supported over Bluetooth. Please switch to Wi-Fi when uploading offline files.
