Error using mkdir but not using !mkdir

I'm running Matlab 2019b on a MacOS Catalina (10.15.5) and I am connected to a University Network drive which is mapped using Samba ('smb://') to

/Volumes/research-data/PRJ-dasa

I'm using a Matlab application (Brainstorm) which must create new directories within this project dir. However, when it tries to do so it results in the following error

>> cd /Volumes/research-data/PRJ-dasa
>> mkdir somepath
Error using mkdir
Read-only file system

However when I try to create the directory using either of the two following lines, the directories are created just fine.

>> !mkdir somepath
>> system('mkdir someotherpath')

So, my question is why does Matlab think the drive is read-only, when the system can create new directories without issue?

Your help is very much appreciated.

I have the exact same question. I am running 2021b on Monterey 12.4 but have the same issue with the smb server. Any insights, anyone?
