10:24 AM		TEAMS NOTICE Some users may have degraded video and screensharing quality in Teams Service Degradation More info: The issue primarily occurs on Teams Meeting Room devices using both Windows and Android but is not limited to these devices.

10:11 AM		TEAMS NOTICE Some users may be unable to open some SharePoint Online list links through Teams on iOS and receive an error Service Degradation More info: Specifically, users attempting to access SharePoint lists through Teams on iOS may receive an access permissions error stating: "Permission required - You do not have permission to open this file."

Additionally, users with access to alternative Teams access methods such as the Teams desktop client and web app can use these to avoid impact. Current status: The service provider has determined that a latent code issue is affecting the request flow leveraged for SharePoint Online list link access within Teams on iOS, resulting in impact. They're proceeding with further analysis to determine their options for remediation. Scope of impact: Any users attempting to access SharePoint lists through links shared on Teams while on iOS may be impacted.
