Tokyo Upgrade Polaris/Next Experience Enabled - Checkbox Selected (Tick Mark) is not visible on the formDescriptionAfter upgrading to Tokyo, the checkmark on checkboxes on the form is no longer visible even though it's checked Release or EnvironmentTokyo CauseThe custom theme being used is missing the OOTB Colors UX Style. https://<instance-name>.service-now.com/sys_ux_style.do?sys_id=a197a38107b03010e03948f78ad30059 ResolutionTo resolve the issue, 1. Open the custom theme record (sys_ux_theme) that is being used on the instance. (check the value of the system property glide.ui.polaris.theme.custom to find the custom theme used on the instance) 2. Under Compositional: App Theme, add the OOTB Colors UX Style 3. You can set the Order as 0 and Type as Core 4. Save the record Note: As of Tokyo Patch 1 (this can also be used in San Diego), it's important to include the Colors UX Style into the custom theme to prevent issues with checkbox styling. It can be added to your theme, with the order as 0 and the type as Core. If this needs to be added as a user selectable variant, create a duplicate copy of the UX Style and add it in as a variant. Additional InformationCreate a Core Color Style and re-use OOTB Styles
