A lot of our users updated to the latest version of Chrome recently... version 58.0.3029.96 and are now unable to add a hyperlinks to images.
I can insert the image fine, but cannot select the image to hyperlink. See the error in the Chrome console below...
If I do manage to highlight the image and click insert hyperlink, the hyperlink is still not successfully applied.
I have raised a case in my private support group, but wanted to also post in this public space to make other users aware. Many of our content creators use this method to create "buttons" and are starting to notice the issue; I've suggested they use Internet Explorer until the issue is fixed.
As an update, reviewing through the case submitted, this behavior is associated with an issue tracked as CLOUD-5113, that you are now tracking through your customer group.
