Under Project Settings -> Chat Notifications, Settings -> Add Subscription
I used to be able to add myself here, using @myusername which would send slack notification to me from the Bitbucket Cloud bot. But now when I try to add myself to new projects, there are no search results and I can't add myself. I can only seem to add channels now. Old projects still send notifications to me like they should and I can see @myusername in the settings. I just can't add myself anymore.
