Hi guys,
Yes like always, there is a few days delay between the availability of the package and the "auto" update from Joomla!
That's just for safety reason... in order to avoid breaking your sites... that's it.
You can choose to wait for a few days OR download the package right away and install it from the Joomla Extension manager... but there is no issue here... that's the correct behaviour.
Regards,
Saba.
