Ytterligare filrelaterade funktioner och problem i Microsoft Teams för företag
Unfortunately, I couldn't find an official statement about this, I've just found this issue occurred today with another user. So It's still a relatively fresh new issue in my opinion.
Having said that, I do believe this issue needs to be investigated furthermore by the MS Team engineering team so they can determine the best next steps for this particular issue.
I highly suggest you report this issue, If this is a bug normally they will release fixes but as a community advisor, I can't guarantee that for you since I don't work for Microsoft.
