Links to Google Maps open a page on maps.google.com which then prompts the user to tap through to continue to the Maps app. This continue to open in app does not work in Orion.
Compare this with other third-party iOS browser interfaces like Firefox.
To reproduce

When you click the blue "continue" button on the Google Maps popup to continue to the app, Orion displays a "could not connect to server" message on the maps.app.goo.gl domain.

In other browsers like Firefox, it will automatically invoke and open the installed Google app.
Selecting Continue to app on a Google Maps link page should open the Google Maps app.
maps.app.goo.gl should load in Orion as it does in other iOS browsers.
