"Login via email code" is also a nightmare on Android. Android regularly kills any processes that are not in the foreground, so I recently went through a whole ordeal trying to login to the MLB app: it requires me to type in an email code, I switch to my email client, get the code, go back to the MLB app, and the page reloads (because it was killed in the background) requiring me to request a NEW email code. I tried this literally five times, going as fast as I could; it seems like it was just deciding to kill the browser process as soon as I switched to the email client, no matter what. This is mostly Android's fault but it's insane and I don't get why I don't hear people complain about this more often
