Can’t update or create contacts in Nextcloud

if hope that @SysKeeper has found a point here. I wasn’t thinking about that app. Though we don’t know what you have installed or not.

Usually there’s a underlaying template here when you open a new thread asking for more details. and last but not least there’s a dedicated support template to fill in.

anyways I would like you to post the link to your yunohost-forum-question here as a reference for future questions so that someone with a similar problem would know where to look for more and maybe helpful answers. @arnauld
