Microsoft Teams: Previewing and Editing Current File Version in Teams

Previewing files in Teams may not reflect the most current edits, even if the modified time shows "Just Now". 

We recommend viewing the file in one of the edit modes in order to view the current version of the document. Click on the ellipses to the right of the file name and select your preferred method for editing the document. Please note that when opening the file in edit mode, the most recent edits may not be immediately visible, but will load shortly.
