If it just pinned the message thread to the top and didn’t change the icon to a giant circle that sometimes doesn’t show notifications, it’d be fine. I pinned my GF’s message thread and I ended up missing lots of messages and notifications from her and ended up unpinning her so the notifications would show up.
Not to mention the comically huge circle icon that is centered when everything else is left aligned.
It only made things worse :(
It defeats the entire purpose of pinning.
I had a problem that appeared to be a corner case with Apple Pay. I wrote a paper letter to Tim Cook about it, and within a week got contacted by a staff person in his office. He worked exclusively with me to identify issues I had not considered, and followed up on all of the direct effects and side effects until they were resolved.
