I am using the free version and have been using canvas for a couple weeks now and the availability times haven't been working for me. For example, I am giving a test today and set it to open at 12:40pm EST (which is what I have my settings to), but it didn't open for the students. On the quiz it lists local time and course time, so I tried to adjust it to the course time (which is in MST) but that didn't work either. I would like to set it so that there are specific open and close times, but so far my troubleshooting steps haven't worked. Any help is greatly appreciated.
