This issue occurs when you load a place within Wire that launches the in app browser. As you can see at the top, the text gets all squished up with the top sensor bar, the time, and the battery. 
You can’t see it in the photo, but on the iPhone X itself, where it says “Wire-Support” part of that gets cut off by the “notch”
Thanks for the report, definitely something to fix on our side, @nicorsm something we can easily replace with SFSafariViewController ?
@mikeger I'll take a look.
Fix has been merged into develop.
