As the subject lines indicate, I am for the first time finding myself unable to copy URLs and other code-like entities (such as sample function declarations) into Canvas Announcements. I have found that I can paste them into replies to announcements, but not into the announcements themselves.
I don't remember this ever being a problem before today. I teach computer engineering so it is quite a drag not to be able to paste these kinds of things into announcements. I did some looking and I have reason to believe that it might be a browser-related issue; for reference, I am using Google Chrome currently. (That said, I have used it quite frequently when using Canvas, and this has never been a problem for me before about 9:30 a.m. today.)
