Office 365 notification MC220283 says that Microsoft has retired support for organizations to audit Sway activities. In other words, no more Sway events in the Office 365 audit log. This might or might not be a problem for your tenant, depending on how much use you make of Sway and if you have the necessary licenses. But the real problem is the lack of communication before Microsoft removed the feature. That’s not good.
