Activity Stream Comment Input Not Visible in Agent Mobile App Issue: Users cannot add comments to the Activity Stream widget on custom table record screens in the Now Agent mobile app. The comment input overlay does not appear, preventing users from posting comments in either online or offline mode. Root Cause: The Activity Stream widget in the mobile app requires the standard field element name comments (without table prefix) to activate the comment input interface. When a comments field is created via the standard table UI for a custom table, ServiceNow automatically prefixes it with u_, creating u_comments. This prefixed field name is not recognized by the native Activity Stream component, which only activates for the unprefixed comments element. Resolution Two resolution paths available: Path 1: Modify Existing Dictionary Entry (Recommended) Navigate to your instance: sys_dictionary.doFilter for your custom table and locate the u_comments dictionary entryEdit the entry and change the Element field from u_comments to commentsSave the changeClear browser cache and refresh the mobile app Path 2: Create New Dictionary Entry Navigate to System Definition > DictionaryCreate a new dictionary entry with: Table: u_assets_review (or your custom table name)Column: commentsType: Journal Save and publishRemove the old u_comments entry if no longer neededSync mobile app
