GUI issues on iPhone 5s

When entering the detail page for a certain network, the Navigation bar disappears meaning there is no way to return to the main screen except by closing and restarting the app.

(The screen for “Add network” is displayed with a Navigation bar containing a “< Back” button".)

Also, the text “More network information available one connected” does not fit within the screen width in portrait orientation.

Version for ZeroTier One not displayed.

It seems to be a failed attempt to use modality.

However, there are multiple mistakes:

  • This approach does not work in versions below iOS 13.
  • And, “Always include a button that dismisses the modal view”.
