I woudn't hold my breath for ANY kind of response from Nokia. I purchased an app from the Ovi store awhile back and I'm not able to download it. I keep on getting a "download failed" error. I sent them a ticket requesting help and I haven't heard a peep from them and it's been over 2 weeks.
In regards to Public Transit, if there is an easy way to add those new countries & cities don't expect them to do it or even acknowledge your emails asking about it. It seems that they have been told to completely ignore the N9/50 and to not respond to customers who have questions or problems.
Really poor customer service from Nokia. They truly deserve to go into the dustbin of history along with their atrocious Lumia trash.
