Theme / Child Theme Update Notificaton

Is the WP Theme Update notification installed on the Parent. I don’t seem to have gotten any notifications.

More importantly, I’ve made modification to the child theme and do not see the typical notification in the WP back-end next to Appearance or next to Updates in the main menu. It is hidden inside APPEARANCE | THEME | Theme Detail.

HELP please.

IS THERE ANY SUPPORT HERE.

Theme UPDATE notification is NOT working for main theme and therefore for the child theme.

I thought this theme was supported and used by you guys on ALL your projects.
