Apple does better than the Android experience described in the article, but it also isn't perfect. There are apps that don't recognize that you need a password and are difficult to trigger the autofill (especially with a third party manager), and on very rare occasion it fails in the browser, too. It handles multi-page passwords just fine though.
Not trying to measure dicks or whatever, just giving a point of comparison. Without investigating, I wonder if some sites/apps don't correctly indicate to the browser/OS that they're passwords and what they're for. I haven't had real issues on my Android reader with proton pass, though that isn't a huge set of apps I use.
Can’t change the default match pattern that iOS uses or add apps to the URI match in Bitwarden iOS. Makes for a few extra clicks on some apps and sites.
