Hi
My name is Daniel. I am an Independent Advisor and consumer of Microsoft products, I will be more than happy to help you.
First of all, I want to let you know this is a peer-to-peer forum meaning I'm just fellow regular MS Team forum users like you who are trying to help other MS Team forum users with their MS Team issue. So in this case, I'm Non-Microsoft Staff I don't have access to your account nor I'm authorized to do so. I hope we can have a mutual understanding from the beginning to prevent misunderstanding.
May I ask, when happens when you use the snap camera with similar apps like Zool call, Skype?
