Not able to use on iPhone XS MAX

When editing dashboard the home bar is in the way of doing anything. Needs an update for new phones!

Completely Unusable on Xs Max

A number of the controls are directly underneath the new “home button” at the bottom of the screen, so when trying to use them, the app is closed — which means disconnection from the Kestrel device, and having to start what you were trying to do from the beginning.

Everything is also sized incorrectly (“squished” from the right side in, as if it were stretched from intended use on a smaller screen).

Export functions also do... nothing; Not even error message.

Update broke the layout

It looks like the latest updates changed the UI to a fixed size that no longer accounts for different resolutions/aspect ratios. The interface looks absolutely terrible on my 6s plus.
