I have published a Chrome extension, uploaded all the required images, including icon and promotional images (which were approved).
The resulted icon appears of much lower resolution (blurred) than the uploaded one. In the search list, the extension image appears as the low resolution icon, instead of either the promotional image or the updated icon.
I can see the majority of the other extension search images displayed correctly (very few are similar to mine), so I understand that this issue is common to a few developers only.
You can see below a comparison between mine and a correct one.
Would you please help me fix these issues?
