HikaShop update alert

-- HikaShop version -- : 3.2.1
-- Joomla version -- : 3.8.3
-- PHP version -- : 7.1.12
-- Browser(s) name and version -- : Chrome 63

Hi guys,
Please, I don't understand how should work the HikaShop update alert into Joomla Update.
I mean, during the last updates I never been adivised from the Joomla Update that there is a new HikaShop version.
PS into Extensions > Update Sites: HikaShop ( www.hikashop.com/component/updateme/upda...v/file-extension.xml ) is enabled.

For example, right now I have installed the 3.2.1 and no messages tell me there is available the 3.2.2 (while I'm been advised for HikaSubscription new version).
Also if I go into HikaShop Update / about and check, tell me the version 3.2.1 is the last one...
Please, Am I missing anything ?

Then, technically, update HikaShop through the Joomla Update system or download the package and install it via the Joomla installer is exactly exactly the same thing or not (any small differences) ?!?

Hi Nicolas,
concluding the speech, technically, update HikaShop through the Joomla Update system or download the package and install it via the Joomla installer is exactly exactly the same thing, right ?
Or, Are there any small differences ?

Hi guys,
really an annoying thing, seem the situation with HikaShop Business 3.3.0 and HikaSubscription 2.1.0 is still the same, no update alert into Joomla Update.

Please, definitively, Do we have to consider the feature as removed ?

Sorry, I thought the waiting was an exeption related to the new HS 3.x
