work with adobe indesign althought its not locked?

Hello!

We recently found out that adobe indesign documents are not locked anymore in wrike when open with document editor. So everyone can open and edit it at the same time.

Can anyone help us and give a tip how to cope with that? How du you make sure nobody else is editing a document while its used by another person?

we are not working with creative cloud (would there be such a function?) - and we work with an older version of indesing (CC 5.5)

Many thanks!
Helga
