Dear Justin,
Good day!
Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description regarding "Why does Teams prioritize Twitter meta data tags over OpenGraph/Schema definitions? ". I would like to share some information with you, we belong to Microsoft Forum Community mainly focused on Micrsoft Teams built-in and basic Functionality and Microsoft 365 Exchange online only. Therefore, we provide some limited knowledge about some aspects of Teams development or Script related scenarios. For your concern we have a dedicated team with special expertise in Teams development and Script related queries, So, we would recommend you to kindly post your query to Microsoft Teams Development support Forum via Microsoft Teams Development - Microsoft Q&A Engineers who are dedicated into this environment with rich experience and more resources can then assist efficiently. We believe they would conduct in-depth research on this query and provide you with more professional assistance. Thanks for your understanding! Your patience and cooperation will be highly appreciated.
Best regards,
