convertg version 3 to version 2

hej
After version Musescore 3 it is very annoying that I cannot save in version 2. Or can I? I do not like version 3, and want to use version 2. All my files are version 2, but unfortunately I have saved a few in version 3. Those I want to open in Version 2
My comment is. Why do they make version 3 worse than veersion 2. Why did they take Songbook away. Since this program has been sold it is gone worse
