Hi. I am using Scrivener 2.7 and Word for Mac 2011. After I compiled using “compile for .docx” my new Word files are created in “compatability mode.” Is this normal? and might this lead to formatting issues down the line? Many thanks for any help, aaron
Yes, this is normal, and it is nothing to worry about. 
The warning message should have a button to upgrade the document, it’s fine to do that, and will mean the next person down the line probably won’t see it.
Thank you!
