Bug Fix Bulletin — v53.0.0 September 2025

Text Tiles

Font weights not rendering correctly

Certain font weight variants — including semibold and extra light — were falling back to a default weight instead of the configured value, in both the Builder preview and the Viewer. All configured font weights now render correctly for default and custom fonts.

Personalized text showing incorrect values on share links

Share links were displaying stale or default text instead of the correct personalized values configured by the creator. Personalized text now displays correctly on all share links.

Personalized text fields not working after converting a microapp from Builder 1.0 to 2.0

Microapps converted from Builder 1.0 to Builder 2.0 were losing their personalization field configurations, causing personalized text tiles to not function as expected after conversion. Personalization fields are now correctly preserved and applied after conversion.

Fonts in Use section not loading reliably in Builder 1.0 and Builder 2.0

The Fonts in Use section was not consistently displaying the fonts actively used in a microapp, in both Builder 1.0 and Builder 2.0. This section now correctly and reliably populates with the active font list in both versions.

Scroll Tiles

Undo hiding the “Done editing” button in nested scroll tile editing

While editing inside a nested scroll tile in Builder 2.0, performing an undo action was incorrectly hiding the Done editing button, leaving the creator stuck in the editing state with no clear way to exit. Undo no longer affects the visibility of this control.

Dragging an asset into a nested scroll container changing the parent container's background

When dropping an asset into a nested scroll container, the background of the parent scroll container was being changed instead of the target container. Asset drops now correctly scope background changes to the container the asset was dropped into.

Microapp Operations

Converted microapps not showing background thumbnails in the Library

Microapps converted from Builder 1.0 to Builder 2.0 were not generating or displaying background thumbnails in the Library and preview contexts. Converted microapps now correctly generate and display thumbnails after conversion.

Duplicated microapps failing to export

Microapps that had previously been duplicated were failing on subsequent export attempts. Duplication and export now work correctly together across both standard and nested scroll microapp configurations.
