This list is filled with duplicate reasons (1 & 8, 5 & 6) and includes nonsense reasons like Safari working on old version (but only if you allow insecure old versions of the browser, which is Chrome would also 'allow')
Two problems with safari: it doesn’t update separately from the os and not every website works properly in it. Have to keep Firefox and/or Chrome around for such edge cases. Is there different for (complex) web applications as that has been browser specific in the past?
Blows my mind that websites can’t work with iOS up to revision…. There sorts a lot of such platforms out there.
