Dear Pablo,

Thank you for your reply.

I just search wiki not the mailing list. I never used \setupnote before.

I would say that LMTX is causing an issue here (but for sure Hans knows
better).

The issue with your MWE is solved by adding:

\setupnote[footnote][width=\textwidth]

It works fine.

Thanks again.

Best regards,

Dalyoung
