Using the Modern engine and the keep-token tags {{Sig_es\_:signer1:signature|keep-token}}, the tags are not being preserved as soon as I switch the document in production. I've been checking every documentation and tried to generate the document via api and via webform, the result is the same : even though the tags have the keep-token in it, they are not shown in the generated DOCX. Anyone having the same issue?
Since the process uses the Modern template engine, please try changing the tags to the Modern syntax. Token names containing special characters should be enclosed in square brackets rather than escaped with a backslash.
