MS Teams for Mac errors on uploading folders

It looks like the MS Teams for Mac client has an issue with uploading folders when using the Upload button.

I had a user who was reporting having problems uploading files to Teams and when I sat down with the user, we had no problems doing the Drag and Drop of Folders into the Teams channel, but when she showed me how she normally does it, she clicks on the Upload button, selects a folder, and then it returns an error in uploading.

If we do it via Sharepoint's upload, no issue, just using the Teams for Mac app.

Anyone else having similar problems?
