If the home screen of the NHS COVID-19 app says contact tracing is active then it is working.
If you have an iPhone, any lack of animation may be due to a setting in your phone called Reduce Motion. When Reduce Motion is turned on, certain screen effects change or are disabled on your device, including the animation on the home screen of the NHS COVID-19 app.
To turn on/off Reduce Motion:
Go to Settings then Accessibility.
Select Motion, then turn Reduce Motion on or off.
If you do not have an iPhone, or this is happening when Reduce Motion is off, report a technical problem using our online form.
