If you are using the Capture Pilot app on an iOS device in combination with running Capture One Enterprise you have the option to display the Grid on top of the image viewed on the iOS app screen. The Grid can be toggled on and off in the Capture Pilot app by tapping on the Grid icon at the bottom of the app screen. It is worth to point out that the visibility in the app is controlled independently of whether the Grid is enabled or not in Capture One Enterprise. This means that the same Grid can be hidden in Capture One Enterprise but visible in the Capture Pilot app or vice versa.
You will need to update the Capture Pilot app (version 2.2.x or later) to enable the Grid functionality. Also, note that Capture One Enterprise controls the type of Grid used. You cannot change the grid on the connected device, you can only toggle the visibility on and off.
