I have been trying to send course invitations from the course people section. Every time it shows me that the invitation has been sent but I dint get any emails. I have published the demo course before sending the invitations.

Also in the course I dint find any option for join code neither it gives me any link for new students who dont have any emails with canvas.

This course has enabled open enrollment. Students can self-enroll in the course once you share with them this URL: https://www.lms.unive.one/enroll/9433P4 fewer options
