I opened a word doc file in a SharePoint library via a channel tab in MS Teams app. I closed the app without making changes. Now when I try to delete the file from the library I get file locked by another user. When I try to delete the same file form SharePoint in my Edge browser, it says it is locked by me.
I have tried to "take ownership of the file" via the library settings but it does not show up in the list of "files which have no checked in version" I cleared my browser cache and rebooted but it didn't help.
Please do not offer solutions that involve PowerShell or designer or code... I shouldn't have to write code to use SharePoint.
