No notification after exposure match

[dylansealy]

Describe the bug, issue or concern

I had an old notification from 16 days ago that I deleted in the app. After a few hours I heard from someone that she had received a notification, so I checked in the app, but I didn't receive one. However, on further inspection I saw in the COVID-19 Exposure Notifications settings that there was a match in one of the exposure checks.

To Reproduce

1. Delete an old notification in the app.
2. Receive a match in an exposure check.
3. Don't receive a notification in the app.

Expected behaviour

I expected that I would receive a notification in the app.

Thanks for your report! A match in the Exposure Notification settings doesn't always result in a in app notification. It can also be a low risk exposure. Duration/distance are playing a role here. If you've been exposed to someone for a short period of time, this can lead to a match but won't trigger a notification.

Not sure if that's the case here. We will have a look to see if we can reproduce it / see any issues.
