In the main Canvas notifications, I have discussions and discussion posts both set to daily summaries.  My email at the top of the column is my normal regular email that they were coming to last semester.

In the course, I have daily or weekly emails set for everything except announcements by me, and all submissions, although submission comments are turned on.  Do I need all submissions on?  I don't see a reset to reset the course to whatever the default should be.

What do I need to do to get emails about comments to posts from other students (so I can know somebody replied so I can reply to them), and to know about comments on my assignments from my instructor?

I've checked my spam folder and there's nothing from Canvas in it.
