I am an instructor for a 4-year University. For the last few weeks, there have been issues with the In-Box remembering that I already read a particular message. Usually, once I read a message and click the blue circle (which then goes white) it stays with that status. Remember, even though I read the message and click the blue circle (which then goes white), it shows blue again when I return to the In-Box. Is this a programming issue or am I doing something wrong? FYI: I've used Canvas for seven years and this issue just appeared within the last month or so.
