Displaying your screen content to others during a Teams meeting or call for collaboration
Dear Matt,
Thank you for the reply and screenshots.
As you mentioned you are not able to recreate the issue from your side and you also suspect that there might be the issue of internet.
Moreover, I would also like to ask if the Teams App that your colleagues from Singapore and Barcelona are the latest version of Teams or not?
From your 1st group of screenshots, we can clearly see that there is some lagging while using the Whiteboard annotations in Teams.
From your 2nd group of screenshots, we couldn't reproduce the same scenario that was being observed while you're having the meeting.
In such scenario, I would suggest contacting your admin and ask him/her to submit the support ticket via below link:
or reference: How do I find my Microsoft 365 admin? - Microsoft Support
Let admin help you create a support ticket in Microsoft 365 Admin Center>Support>New service request.
The support team there has the correct escalation channel for this case. They have higher permission to remotely assist you.
This is also the most efficient way in handling this kind of issue.
I appreciate your patience and understanding and thank you for your time and cooperation.
Sincerely,
AJ RAJ| Microsoft Community Moderator
