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.
