Dear @Jane Zhang,

Thank you for providing the detailed information, logs, and exact timestamps. Based on our review, your Poly Studio X70 is successfully joining Microsoft Teams meetings, with audio and participant video continuing to function normally. However, after approximately 30 to 50 minutes, the system is no longer able to display shared content while the meeting itself remains active.

Since the issue persists after rebooting the system and updating all components to the latest available software versions, this does not appear to be related to local configuration, user settings, or network connectivity. At this stage, further device‑level troubleshooting is unlikely to resolve the issue.

In this scenario, the best next step is to reach out to your IT administrator and request that they create a support ticket with Microsoft Support directly from the Microsoft 365 Admin Center. Creating the ticket from the Admin Center allows Microsoft to review Teams Rooms–related logs and investigate the issue more deeply in coordination with the device vendor if needed. For reference: Get support for Microsoft 365 for business

If you are unable to reach a Microsoft support agent through the Admin Center, I recommend reaching out to Microsoft 365 operated by 21Vianet, as they provide localized support for certain Microsoft 365 environments. For reference, you may review the following resources: Microsoft 365 operated by 21Vianet and https://en.21vbluecloud.com/

I hope the information shared helps point you in the right direction. Thank you for your patience and understanding. I'm looking forward for your reply.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.
