COVID Alert update now lists dates alongside multiple exposure notifications The CDS explains that the new system will help distinguish multiple exposure notifications and ensure people know when they've been exposed Canadian Digital Services (CDS) rolled out a new release of the COVID Alert app that can now display multiple exposure notifications from around the same time. In a series of tweets, CDS explained how the change would help Canadians using COVID Alert. Before the update, the app would notify people about one exposure at a time. In some cases, when someone was repeatedly exposed in a short period of time, that could mean those exposure notifications aren’t clearly differentiated. With the update, COVID Alert now distinguishes multiple exposures.
