Customizing the visual backdrop during video calls to enhance privacy or presentation
Dear @Gabrielle Denman,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, after updating Microsoft Teams, the Green Screen toggle is no longer available even though it was previously working.
For better understanding your situation, could you please provide some more information as:
Which version of Teams are you using (Teams desktop app or Teams web version)?
Does the issue occur on other devices or only this one?
Are you checking the option with the camera turned on?
Are you using a personal account or work/school account?
And are you using the newest version of Teams?
Please understand that the more information you provide, the more effectively I can support.
For reference Use a green screen in Microsoft Teams
Looking forward to your update.
