Many websites cannot be extracted correctly for their icons in Enpass even though I can see them in my browser.
I suspect that you are only attempting to extract the "favicon.ico" from the website root directory, right?
Could you please also try to extract the data within the "<link rel=icon />" tag on the web page?
Let me give you an example.
For instance, on https://www.getflix.com/, the website does not use "/favicon.ico" as its website icon.
Instead, there is a tag in the meta of the webpage that accesses a PNG image file located in the "/assets" directory.
However, it seems that your website icon capture function does not read webpage content.
I strongly hope that you can improve in this aspect.
Thank you.
