Title has it. See attached. Reproducible by rotating the app while the keyboard is up. Tested on an iPad Mini
Been working on this issue for a couple of days. I refactored the screen using Storyboard and Autolayout to make it "future proof". Was a bit challenging but all seems to be working perfectly.
Also looks like the Jetpack logo is squished on the iPad Pro:


So testing this out more on the iPad Mini, it looks like the layout issues are mostly resolved on 10.0, 10.1, and 10.2 sans the Jetpack logo issue noted above. I will post a PR to address that.
I did catch another issue when rotating the device with the soft keyboard up and then dismissing it:

The login form can be pulled down below the bottom screen edge. Doesn't happen 100% of the time, but enough to warrant a fix.
Closing this in favor of #6389 — the team agreed to completely refactor this screen.
