Hi @Ngo Duy Nguyen
Could you please tell me: have you tried to click on the link for login operation, and then check whether the shrinkage diagram is displayed?
In Microsoft Teams, there may be several reasons for linked previews that sometimes not display video shrinkage. Please try the following possible solutions:
Clear Teams cache:
Check the video format: View the ability of the video shrinkage map may also depend on the video format, ensuring that the video format is a common format supported by Teams (such as MP4). According to our test, the first link you provided is the transit link, so it will be displayed as a logo.
Use Teams web version: If there is a problem with the desktop version, you can try to use Teams's web version to see if you can display the video tap map normally. https://teams.microsoft.com/v2/
