Canvas Notebook interface strings are not localized in any language: untranslated UI strings and English date formatting across all locales

InstContentTeam

Engineers are currently investigating the issue.

Summary:

Nearly every string the new Notebook feature renders displays its English source text regardless of the interface language, on both the main Notebook page reached from course navigation and the Notebook side panel opened from a course content page. Dates beneath saved highlights render in English short date format rather than the format appropriate to the active locale. Under Japanese, the result count renders as 1の結果, which omits the counter word and reads incorrectly. Expected is closer to 1件の結果.

Expected Behavior:

All Notebook interface strings should resolve from the active locale's translation bundle, matching the surrounding Canvas interface, in every supported language. Dates should render through the locale aware formatter rather than in English short date format. Interpolated strings such as the result count should render grammatically in the active locale, including the appropriate counter word in Japanese.

Steps to Reproduce:

Prerequisites: Have the Notebook feature option enabled, a course with at least one student enrollment, and the course language set to a language other than English.

Main Notebook page:

1. Act as a student enrolled in the course.
2. Open the course and select the Notebook item from the course navigation menu.
   1. Observe the label above the filter dropdown, which reads Filter in English, and the dropdown itself, which reads All notes in English.
   2. Observe the result count to the right of the dropdown, which does resolve to the active locale.
3. View a saved highlight assigned to the Important category
   1. Observe that the category chip reads Important in English.
4. View a saved highlight assigned to the Unclear category
   1. Observe that the category chip reads Unclear in English.
   2. Observe the date beneath each highlight, which renders in English short date format such as Jul 31, 2026 rather than in the format appropriate to the locale.

Notebook side panel:

1. Open a course content page in the same course that contains highlightable text.
2. Open the Notebook panel on the right side of the page.
3. With no saved highlights in the course, observe the panel empty state
   1. The heading reads Start capturing your notes and the paragraph beneath it renders entirely in English.
4. Select a passage of text on the page and observe the context menu that appears
   1. The options read Mark unclear and Mark important in English.
5. Select one of those options to create a highlight, then locate it in the panel and observe that its category chip and its date render as described in the “Main Notebook page“ above.
   1. Observe the note entry placeholder on the highlight card, which reads Add note (optional) in English.
6. Select the pencil icon to open the note entry field
   1. observe the action row beneath it, where both buttons render in English as Cancel and Save.
7. Select the trash icon on the highlight to open the delete confirmation.
   1. Observe that the confirmation buttons render in English as Delete note and Cancel.
