Why isn't Canvas is letting me edit the assignment group weights in assignments?

[RachelSalmon · Accepted solution]

To edit the assignment group weights, click the three dots to the right of the +Assignment button and then click Assignment Groups Weight. You should be able to edit the percent values on that pop up. If you cannot, try doing so in another browser to see if it's a cache/cookies issue. I have also found that sometimes little glitches will happen if my browser is out of date so check for updates as well.
