Dear Hans,

The following file:

\setuplayout[location=doublesided]
\setuppagenumbering[location=inmargin,alternative=doublesided]

\starttext
\dorecurse{20}{\input knuth }
\stoptext

using:
> ConTeXt  ver: 2021.04.21 11:39 LMTX  fmt: 2021.7.11  int: english/english

the left page of the double spread places the page number on the right margin of the page and in the right page it is placed on the right margin


using:

the left page of the double spread places the page number on the left margin of the page and in the right page it is placed on the right margin. This is what I would like to get in LMTX as well. Am I doing something wrong here?

Thanks,
Charlie
