Thank you for your post!
Can you confirm that the emails are not being sent to your Spam Folder?
Can you try:
1. Unchecking the options for email and the community digest
2. Logout of the Community site
3. Log back in
4. Recheck those options to receive emails
Thank you. I received the community updates for January 28, so I hope all is well now.
If it happens again, I will take the actions you suggest, to uncheck and recheck the option boxes. I think I did that while I was trying to figure out what was happening, but I didn't log out and back in between unchecking and rechecking. But something seems to have worked.
