A few tips for working with CWA and the CrewWeb app:
By logging out, you reduce the load on the company’s CWA servers and avoid unpredictable behavior after a period of inactivity.
Again, this will avoid unpredictable behavior after a period of inactivity.
Because of the small-device-unfriendly CWA interface, trips and buttons are too small to be tapped reliably. Zooming in makes them larger so that you can actually tap the right thing. This is especially helpful for multiple taps.
What’s ‘important’ is up to you. Since CrewWeb is not an approved web browser, you will have no recourse if something goes wrong while using it with CWA.
