When my colleagues and I use different versions, it will be very difficult to share files because of the saved files in different versions. If the latest version of the software can default to the old version of the colleagues, it is convenient to share files.
For example, I use the 2022 version, and my colleagues use the 2019 version. If I save the file, I can save the 2019 file by default, it will be easy to share files between us. You can save the 2019 version file with Save As, but that's too much trouble.
