Collaborate Session Time Appears To Be Displayed At Wrong Time.
The Times Listed For Collaborate Sessions Appear Hours Ahead Of The Actual Time When Viewed In Browser
Some users have reported that browsers freeze, or become unresponsive, intermittently when sharing an application, or sharing their screen in Collaborate Ultra on Windows. This issue does not affect all users and does not occur during all sessions. The issue has reportedly occurred while using different browser versions on Windows.
Symptoms:
SYMPTOM: Sometimes, when users go to access their session, they find it has already ended.
Collaborate Ultra uses the end user's computer's local system clock to display the session time to the user in their preferred local time zone. Sometimes however the local system clock gets manually changed or out of sync in a way which results in Collaborate Ultra not showing the scheduled sessions correctly. For example a session that should be at 2 pm local time is shown as starting in the past at 12 pm.
Affected Platforms
Affected Operating System: Windows
Affected Chrome Version: 88.0.4324.96
Solution/Workaround
Check the computer's system clock preferences and resynchronize with a server to ensure time zone, date, time and daylight savings is set correctly.
Windows: go to Start > Settings > Time & language > Date & time and click on Sync Now
Check that the user has selected the correct time zone and has the correct daylight saving settings.
Check that the Windows Time Service is running.
- Go to Control Panel > Administrative Tools > Services.
- Scroll to "Windows Time"
- Status should show "running"
- If Status does NOT show "running", double click on Time Service to open the Windows Time Properties Box
- Set Startup Type to "Automatic"
- Under Service Status, click "Start"
- More information on the Windows Time service found here: https://docs.microsoft.com/en-us/windows-server/networking/windows-time-service/windows-time-service-tools-and-settings
Mac OS: Apple menu > System Preferences, then click Date & Time Unlock to make changes, Select Set date and time automatically and choose an appropriate server for your region. Click on the Time Zone tab to select the appropriate Time Zone.

PROBLEM: Intermittent issues with audio and video in some breakout groups
This issue does not affect all breakout groups and does not occur for all sessions. In a session with more than 2 breakout groups, in some cases, members of some of the breakout groups are unable to hear each other's audio or see each other's video. Other breakout groups within the session will be unaffected by this issue.
Symptoms: Members of the affected breakout groups may not be able to hear each other's audio or see each other's video.
Resolution/Workaround: A workaround for this issue is to move all members of the affected breakout group into another breakout group. The other breakout group may be an existing group that is unaffected by the issue, or a new breakout group can be created.
