The pingdemic slams the brakes on UK's Covid recovery as workers and shoppers are left stuck indoors
Close to 700,k people were pinged by the NHS Covid app in the week to July 21
Many forced to self-isolate have received both their vaccines, or turned out to be healthy, but still have to stay off work for up to ten days
The app has hurt sectors such as retail and hospitality and many businesses have been forced to close again
