Downloaded files aren't highlighted in File Explorer
Please select the file that was downloaded when clicking the "file was downloaded" window that brings up File Explorer.
The issue is that downloaded files aren't selected when clicking the "1 File Was Downloaded" box that appears at the bottom right of the screen.
When you download in Chrome and click on the file you've downloaded, it loads up File Explorer and highlights the thing you downloaded. Try it yourself press "Ctrl+J" to bring up downloads, then click "Show in Folder" on any file. File explorer will pop up and the file will be selected. Teams does not select the file, Teams only opens up File Explorer. So when you click on the convenient "File Was Downloaded" box at the bottom right, you still have to go digging for what you downloaded.
I hope this can be fixed.
