Even if a match had not been uploaded with Serve and Receive Rotation data (or the wrong information was entered), that information can be quickly and easily added or edited after logging:
You get started by clicking on the 'watch' button of the game you need to add the information to...
...then switching to the timeline view of the game by clicking on the 'pen and notepad' icon at the top center of the screen:
Click on the 'Set Rotations' button along the far right side of the screen:
Fill in the game's rotational info (notice you can also change or set the rotational direction, if needed):
Always save your work!
The game's tags will automatically update to incorporate the new rotational data.
