I noticed two issues for the first time today related to the reply box. I’m pretty sure both of these issues are new. I’m not sure if ux is the right category to put this, but nothing is really broken so it felt more appropriate than the bug category.
The first is just a minor styling issue. Notice that the preview button is a bit close to the border. As far as I can tell, the calendar icon is new, so maybe that pushed it over too far. I’m using a standard size iPhone 8 in portrait mode.
The second issue I’ve never noticed before, and now it’s happening all the time. So I’m fairly certain it’s new, but I can’t say for sure. Basically, when I try to scroll the emoji dialog, if I touch the screen on an emoji it can’t scroll. It only lets me scroll if I happen to touch the screen between one of the emojis.
