I too am having the same problem in the "new" EN Web version, which I've started using just recently. Outside of EN, when I am pressing either Ctrl+click and Shift+click, I am able to select multiple items, regardless of whether the items are in a range or not.
As a test, I reverted to the older version and I was able to merge notes without a problem. However, I'd like to use the new EN Web version.
Should I submit a support ticket? Or this a known issue with a quick fix?
Thanks in advance for any and all replies.
