One other small annoyance maybe someone can check if their 17.4 does this. Maybe 17.4.1 will fix. I came from an Iphone XS with super old firmware, and now on a 15 pro with 17.4.
In text messages, say someone texted you today, and you went in and deleted the individual text from them, (this would move the conversation back down your list to say yesterday or the last time they texted you, and that message wouldn't show up at the top of your screen still) Now with ios 17.4, if you delete say all the texts someone sent you today, their message thread still says up at the same spot from the original time stamp that was sent to you. It doesn't know to put that message down in your list further after you delete the single messages. I don't know when that changed? or if it's a bug in the new ios.
Or say you send a new text today to someone that that haven't texted in a few days ago... If you delete your own message that you just sent them after you send it, it still has their message thread at the TOP of your phone, it doesn't push it back to a few days later where it should be.
