What things need to be "ironed out"?
There's bugs all over the OS ... most annoying is still dealing with issues when I try to text boxes (e.g. this forum box).
In safari, some sort of blank screen slides in front of the text box and you can't see what you're typing.
A simple example of when I try to type into the login / password / 2FA boxes for login into these forums. Happens like 85% of the time you try to fill in any sort of text form in Safari.
This is just one of many many many bugs.
