Click: a ticket › Follow

Step 2: Read what changed
When someone comments or moves the ticket, the bell shows "updated a ticket you follow". Click it to open the ticket.

Good to know
You follow a ticket on your own when you file it, when it's given to you, when you comment on it, and when someone mentions you in it.
You never get a notification for what you did yourself.
Turn these notifications off in Settings › Notifications: "A ticket you follow gets a comment or moves".
You can ask Ask Sam: "follow SUP-12" or "stop following SUP-12".
