Yeah I think the store still has some issues as I had trouble reinstalling my apps after using NSU to update to PR1.1 - I initially got a "could not find download" error and then after that I would get download errors when I was installing a bunch of apps at once.

I have a 005 variant and its in the US, I would hope thats nothing to do with it... Its not a deal breaker but it is frustrating that I do not get update notifications - sad but I always look forward to these!

I may open a thread on the official support forums and see what they say...
