I have a workflow that is triggered by a PowerApps button which populates a Word Document with data and saves it into the user's OneDrive for Business.
The OneDrive for Business action has been configured so that it runs as the user:

However, even through the flow runs successfully, it is saving the files to the system admin account that created the flow:

I have tried:
- Deleting and re-creating the connection.
- Deleting and re-creating the action.
- Re-authenticating to the connection.
- Removing and re-adding the Flow to the Power Apps button.
- Reloading the Power App and re-authenticating to the connections as the user.
None of these has worked and OneDrive for Business keeps on saving to the wrong OneDrive.
