Hello,
The "Backup up to date" icon on the Joomla 4 dashboard, always shows as green "Backup up to date", even when it's not actually up-to-date according to the settings.
For example, in the "Quick Icon - Akeeba Backup Notification”, the "Stale backup time, in hours" is set to 24 hours. But even if you don't take a backup for 3-4 days or more, the dashboard icon will always show a green "Backup up to date"
