Fixes

Accessibility and localization

• Fixed an issue where the Zoom label in collapsed header flyouts was not translated.
• Fixed an issue where setting the language in one WebViewer instance would affect all instances.

Annotations

• Fixed an issue where the AnnotationPopup did not show the Align button in mobile view.
• Fixed mobile category selection, added a clear control for selected categories, and corrected upward-opening font menu layering in the custom stamp modal.
• Fixed the Brazilian Portuguese label for the form-fill checkmark tool.
• Fixed a crash when creating an ink signature in a second WebViewer instance on the same page, caused by the signature canvas being attached to the wrong viewer's tool.
• Fixed an issue where canceling a comment after it autosaves would persist the new text rather than returning to the last saved text.
• Fixed an issue where deleting a custom stamp that was actively being previewed at the cursor didn't clear the preview, allowing the deleted stamp to still be placed on the document.
• Fixed an issue with tab contrast and filter button availability within the Stamps panel.
• Fixed an issue where long category text wasn't truncated, so it appears appropriately within the Stamps panel.

DOCX Editor

• Fixed an issue where returning focus to a DOCX document could freeze the Notes panel while a comment and multiple replies were being edited.

Forms

• Fixed an issue where the viewer would jump after deleting a signature from a signature form field.
• Fixed an issue in Safari where users couldn't rename form fields through the form field index panel.

General

• Fixed an issue where selection checkboxes were not visible for nested outlines in edit mode.

• Fixed an issue where repeatedly closing the password modal on added password tabs caused the viewer to get stuck in a permanent loading state.

• Fixed an issue where adding a tab with a faulty URL caused a permanent loading state.

• Fixed tabs that didn't appear correctly when they contained only a label.
• Fixed an issue where tooltips would be rendered off-screen with multiple instances of WebViewer.
• Fixed an issue where page manipulation controls in a standalone Thumbnails panel did not respond to panel width changes.
• Fixed an issue where hover popups could become inaccessible when moving the cursor between adjacent links, causing the popup content to close before it could be interacted with.
• Fixed an issue where embedded print mode could drop grouped annotations and incorrectly include note-thread replies in annotation-only print output.
• Fixed an issue where pinch zooming on mobile and tablet devices could shift the zoom focus when WebViewer was offset within the host page.

Multi Viewer

• Fixed an issue where opening another document in the second viewer would cause the UI to hang on the loading screen.
• Fixed an issue where switching viewers while creating a Polyline annotation would start a second annotation in the new viewer.

Spreadsheet Editor

• Fixed an issue where selecting a hidden spreadsheet sheet from the overflow menu left it hidden and inaccessible for rename or deletion.
• Fixed an issue where resizing the DocumentContainer would cause a gap to appear beside the Search panel.
• Fixed an issue where selecting an empty cell displayed a font size that did not match the size applied when typing into the cell.
• Removed the redundant Main Menu heading from the Spreadsheet Editor hamburger menu.
