[Nextcloud] Can't change (for some users) the privacy of personal info

My YunoHost server

Hardware: OVH Dedicated server
YunoHost version: x.x.x
I have access to my server : Through SSH + through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

I’m trying, for all my users accounts (I have direct access to all these accounts) to change the Full Name privacy lelvel from “Contacts” to “Local”. It worked for some, but some other account won’t save the new value and we stick to “Contacts”. Same goes for all the fields in the Nextcloud personal info page.

Is it something that could be connected to Yunohost?

Thanks a lot :slight_smile: , I’m a bit lost here!
