Issue Status: OPEN

Issue Description: Some users may see that adaptive card messages are incorrectly rendering on multiple lines in Microsoft Teams.

More info: If you’re using RichTextBlock in your adaptive cards with TextRuns that have their selectAction property set, unwanted line breaks show up. Your card, however, remains fully functional.

Current Update: 23/12/2024 09:05:00 AM – Microsoft have discovered the library used by Microsoft Teams to pull the adaptive card messages has an incorrect action definition, resulting in impact once the library version was updated. They’ve updated the library and are working on a new Microsoft Teams build to deploy this fix in. They expect to have a timeline for deployment by their next scheduled update.

Scope of impact: This issue can potentially affect any user that’s viewing adaptive card messages in any Microsoft Teams connection method.

Root cause: The library used by Microsoft Teams to pull the adaptive card messages has an incorrect action definition, resulting in impact.
