Deselect all objects (click somewhere there is not an element to ensure no elements are selected).
Open the ‘Comments’ bar in the bottom right corner by single-clicking on it.
Click ‘Resolve’ by the comment you wish to hide. The comment will no longer show unless the ‘Show Resolved Comments’ option is toggled and will no longer show the blue speech bubble in the upper left corner of an object.
Move the cursor over the comment and click ‘Delete’, under the comment.
If it is an original comment (not a response to another comment), you will be prompted to confirm. Click ‘OK’ to confirm your choice. This will delete the entire thread of comments (the selected comment and all its replies).
