Petty complaint (everyone's favorite, right?): The Spanish government's online identification app is called `cl@ve movil`. My usual way of accessing apps on my phone is to type in their name. Typing in `cla` does *not* bring up the cl@ve app. I forget this every time. Branding it with an @ is fine but, using that in the app name is very mildly annoying. (I told you this was a petty complaint).
Semi-related: I have been considering switching from android to @calyxos but, is there a way to check before hand whether apps like cl@ve movil and my bank will still work? I don't have a good sense of what parts of the os these kinds of things do / don't rely on.
