I just upgraded the owncloud server to 10.2.1-1 (RPM for centos 7.x.) On my iphone I installed the “owncloud - File Sync And Share” app (ver 1.04, dated 4 days ago.) I am able to login to the owncloud server and browse directories. I do not see any options to upload files or auto-upload pictures.
Every time my client scans server for changes, it might take 5-10 minutes.
