Utility icon not showing
am using the below line of code to show the icon but instead it is showing as a dot. Tried on chrome and edge.
The markup within which you are showing the salesforce lightning icons has had a (max) height set for it ; by enlarging the image you can see that you are seeing a slice through, about halfway up the icon:
You need to examine the markup around where you insert your image and check what CSS is being applied.
