I often see, that some passwords from websites or apps don’t have an icon, which helps to find the login credentials. But sometimes there’s no icon, and then it needs more time. I think that is because it tries to take the icon from the first URI.
So if the first URI is from an app, it can’t display an icon, and you have to manually copy & paste them out. For 2 URIs it’s not a big deal, but if you have multiple, it needs a lot of time.
I would be happy, I this feature gets added to all or the most platforms.
