We have observed that in the latest versions of Indesign the way how files are opened has
changed which results in scenarios when lock for the files opened not being created. This
means that if one user has the file opened in Indesign, and the other person opens the same
file, the other person may not be warned that the file is in read-only mode.
This behavior has been observed for Indesign 2023 (since version 18). In previous versions of
Indesign locks were generated correctly.
