It is possible that you have activated Bluetooth and COVID Radar exchange codes, but you still do not receive any information about your positively diagnosed contact.

To do this, it is necessary activate the setting "Notifications of exposure to COVID-19" if you didn't do it when first starting the app.

This is a function that allows the mobile phone to store the IDs of the people you have been in contact with and of notify you if any of them have indicated they have the virus.
