Nextcloud issues with shared folders

Hello, I recently migrated the data folder and database of an existing Nextcloud (Ubuntu snap solution) instance into a NixOS Nextcloud instance. When testing I discovered that I get permission errors when accessing files in shared folders. The relevant configuration: { lib, pkgs, ... }: { # Nextcloud settings. services.nextcloud.enable = true; services.nextcloud.hostName = "localhost"; services.nextcloud.config.dbtype = "mysql"; services.nextcloud.config.dbname = "nextcloud"...
