How can I manage my notifications in Canvas if I am not getting them?
Canvas gives users a lot of control over how they are notified of course updates. You can adjust where and how frequently you receive notifications. To manage your notifications, navigate to Account in the Global Navigation menu (the purple menu on the far left-hand side). Select Notification Preferences to manage them. For step-by-step: https://community.canvaslms.com/docs/DOC-1286.
If you want to receive notifications for your own posted announcements and discussion forum entries, as you did in Cruiser, you will need to select those options in the list (it is not a default).
