Please check if the option: “Foot control” is enabled or disabled.
This can be found in the Central Quick Menu.
Slide the menu open - click on “Lift” - then “Foot control” is at the bottom right side of the menu. In the below example, Foot control it’s enabled (on).
Standard this setting is enabled. If a user disables it, the change will not be saved. Meaning if the screen restarts, the foot control will automatically be enabled again.
