You can override any current restrictions on the virtual keyboard on your Yodeck players based on the Raspberry Pi board, with the following configuration directive.
enforce_virtual_keyboard=true
Setting it to true ensures that the virtual keyboard will function regardless of the type of screen, layout, etc.
The directive must be applied in the Advanced Player Directives on the Yodeck portal, as shown in the image below. Ensure that the virtual keyboard is enabled in the Interactivity tab.
The Advanced Player Directives box can be found in the Customization tab under the Advanced tab.
Important: Ensure it does not overlap with videos or the Ticker app, as this may cause unexpected behavior.
