GUI>Settings>Updates>tick the appropriate box depending on whether you want the vps and/or program updates. 
yes, I like this set
Personally I prefer to do manual program updates. That way I download the entire set-up file just in case something goes wrong.
This gives me the added benefit of not having to re-download in case “Murphy’s Law” goes into effect.
The automatic program updates are spread over longer time period (weeks, possibly months - depends on how quickly we want it to happen), to balance the load on our servers etc.
So it is normal that your program doesn’t automatically update right away - and it has nothing to do with the country.
