If you are unable to resize a group or collection of selected objects on your canvas, the likely culprit is that one of the currently selected objects is a textbox, line or arrow.
If this is the case, you will see a faint message in the top left corner of your canvas that reads "Selection contains lines or arrows and cannot be resized or rotated" or "Selection contains text and cannot be resized":
Currently, selections containing lines or arrows cannot be resized as part of a group and will need to be resized separately.
