WhatsApp has today updated with native screen resolution support for the iPhone XS Max and iPhone XR, in addition to a couple new features for all customers. You can find the new update, version 2.18.100, in the App Store for free.
A month after the iPhone XS debut, WhatsApp now takes advantage of the full 2688×1242 resolution of the iPhone XS Max. This means you can see slightly more message bubbles at a time, and the keyboard sizing will now be consistent with other apps on the phone.
