Crown Convos will be the first option under your profile photo on mobile. On the desktop, it will appear in the gray bar on the left side of your Dashboard.
To start your convo, click "+ Start A Convo" button.
You can use the filters to sort out general notifications using "Timeline" option and also you can filter your own convos using "My Convos".
