That the labels for the apps get truncated so you can only read “Proton” plus the first letter of the app. I’m only able to distinguish based on the icons which isn’t great because Pass and Drive are similar colors, and Pass and VPN, and Drive and Calendar are similar shapes.
All of my icons are circles. Are yours not?
As with all your other questions, it depends on your Launcher
I was just commenting about how it’s half-assed design to just slap an existing icon against a white background and call it a day. Compare to the lawnchair icon, locus, or even the Lyft icon in your screenshot. You find the names annoying, I find the design laziness annoying. Companies do it on iOS as well (including Apple).
I imagine part of it on Android is for adaptive icons https://developer.android.com/develop/ui/views/launch/icon_design_adaptive
