[Q] Note 4 updates not working? topic

Hello, I have purchased the Note 4 in the US (unlocked) and I am using it in Europe in the Czech Republic. There was not a single update since I purchased the phone (November 2014) while I have read several times Note 4 received some kind of an update. Also, the phone received Android 5 in all of the US and the Czech Republic already (at least I have read that now on Sammobile) so I am wondering - did I block the device´s ability to receive any updates by using it in a different country? Does anyone have similar experience with this or other high end phone?

I did exactly the same thing with the Galaxy S4 two years ago and it received several updates right after purchase and also during the following two years. Now Note 4 which is also a high end device (though more niché) and not a single update yet. As of 18th May 2015, the device says the latest updates were installed and the device status is "official".

I prefer using my device the official way so I didn´t really care about flashing but if I have to use a firmware that was never updated since the phone release, I will flash it (as a last resort).

PS.: Sorry about posting this if it does not belong here. Google is not that powerful yet to redirect me correctly and I didn´t quickly find any info about what to post on this forum. It is likely my post belongs somewhere else but it would take hours of research to find out where, so sorry and thank you so much for your time.
