We have been made aware of a number of reports of people not being able to access files within various Microsoft Teams spaces or SharePoint sites that they expect to have access to. We are working with Microsoft support to better understand the issue and work towards a resolution, but do not have a timescale for this yet. There is no confirmed workaround identified at this time, but using a private/incognito session on a web browser can help to avoid issues with cookies.
