[Adobe InDesign 19.3.0.58] [macOS 14.4] Network share files read-only

Hello,

A client of ours uses Adobe InDesign and, for about 1.5 weeks now, every time when working with InDesign files from a Synology NAS he gets that they become read-only. When opening a file from the local drive this is not a problem.

InDesign is up to date as is macOS.

What things can we all do to solve this problem?

I would love to hear about it.

(p.s. Adobe InDesign has full disk access in privacy/security)
