By default, all YouTube tiles will have a standard white play icon for the videos, like seen below:
You have the ability to change this to a custom icon. For best results, we suggest using a transparent image like .PNG or .SVG format.
How to change the default Youtube icon:
Select the video tile
On the left pane go to PLAY ICON section
Select Custom Icon
Upload the new Youtube icon from your Media Library or from your computer.
