I have received a notification about “COVID-19 exposure logging”, “COVID-19 exposure notifications” or “Possible COVID-19 exposure” - what does this mean?
The NHS COVID-19 app uses Apple and Google Exposure Notifications. When exposure logging is switched on, Apple or Google may send you notifications. These may be called COVID-19 EXPOSURE LOGGING or COVID-19 Exposure Notifications. Sometimes it may seem as though these messages disappear, or you cannot click into them. These are default messages from Apple and Google. There is no need to be concerned if you miss or overlook them. You're currently not able to turn off these default Apple and Google notifications. Important messages from the NHS COVID-19 app will always be visible to you from inside the app.
