Known Issues 

Microsoft Teams Rooms on Android (MTRA):

• Device Information Display Discrepancy on Mate PoE Menu 
  • When a Mate PoE is upgraded to AOSP-compatible firmware and paired with a D7X Android (D7X-A), the Mate PoE's Menu Device Info page may incorrectly display the Microsoft Intune version and Microsoft Authenticator version information for the D7X Android (D7X-A).
  • Quick Fix: Upgrade the D7X Android (D7X-A) to AOSP-compatible firmware to align with the Mate PoE’s updated firmware.

• Teams Main Interface Displays Black Screen During DTEN Orbit Mission Control (OMC) Session
  • When DTEN Orbit Mission Control (OMC) is used for remote assistance by DTEN Support, the Teams main interface may appear as a black screen on the connected remote PC. This behavior is due to a newly implemented security policy within the Microsoft Teams application.
• Audio Stability Issues in Teams Meetings
  • Intermittent audio issues may occur during Teams Room meetings, including unstable volume, occasional echoes, or brief audio dropouts. This condition typically resolves itself without user intervention. If the audio issues are not resolved, contact DTEN Support for review and assessment. Additionally, please ensure the D7X Android (D7X-A) is on the most current version of the Teams Room App available in the Teams Admin Centre (TAC) or Pro Management Portal (PMP).
• Whiteboard Writing Responsiveness
  • When using the MTRA Whiteboard, users may experience uneven or delayed stroke response, particularly in the lower section of the whiteboard. This issue will be addressed in a future MTRA App and DTEN firmware release.

Zoom Rooms on Android:

• Relay Speaker
  • The device may experience disconnection of the Relay Speaker after a power cycle or during prolonged meetings.  
  • Quick Fix: Power cycle the device or the Relay Speaker, or reinsert the wireless dongle.
• MacBook Screen Sharing Black Screen in Zoom Rooms
  • MacBook users may encounter a black screen when sharing content via a Type-C USB cable in a Zoom meeting. This issue is more likely to occur if the MacBook enters sleep mode during the session. 
  • Quick Fix: Update the MacBook operating system to the latest available version. If an update does not resolve this issue, adjust the MacBook's sleep settings.
• System Freezes
  • The entire system freezes after the device exits a meeting, though this occurs with an extremely low probability. 
  • Quick Fix: Power cycle the device.
