I get no quotation marks at all (and no protrusion) with \quotation{text} using \setupquotation[method=font]. This seems to have started earlier this month, but for the record, I am using ConTeXt ver: 2021.06.24 19:19 LMTX.
Wolfgang's example from a related thread earlier this month
(https://www.mail-archive.com/ntg-context@ntg.nl/msg98669.html)
should have quotation marks and protrusion for the third line,
matching the second line.
\definefontfeature [default] [default] [protrusion=quality,expansion=quality] \setupquotation [method=font] \setupalign[hz,hanging] \starttext oh hi there “you are so” \quotation{you are so} here here \stoptext
Similarly with \setupquote. Help, please!
