There seems to be something wrong with both the icon and logo assets provided.

• The icon assets looks blown up. Do we have a higher resolution version available?
• The logo looks like the icon with some transparent space added on the sides.

Recommendations:

• Add a higher res icon
• Remove the logo version (we will automatically fall back onto the icon provided).
