You're stating that as if it's fact, I have no issues with Cortana here in the UK on either WP8.1 or Windows 10. That doesn't mean that others have no issues, give me specifics about what isn't working and I can help but just saying Cortana is "crap" in the UK doesn't help. The only notifications I get on Windows 10 are for football results, everything else just shows on the Live Tile.
Cortana did have issues here in the UK when Windows 10 launched but those should be fixed now, it might also be that because I use Windows Phone the settings were pulled in automatically for me which is why I had no issues.
My issue(s) is that she has been advertised on TV to tell me when to leave for an appointment. If it's on TV it must mean its easy to set up. She sometimes tells me when to leave for work, but not every time. How can you rely on an intermittent assistant?
Is the "leave now" function reliant on it being a business appointment? The ads and web promotional stuff don't qualify, so I assume its any appointment I add to my calendar - you can't add reminders in Cortana that use a time WITH a location, so calendar is the only place to set this up. Yes I have places set as Favorites in Maps. But it still doesn't work as promoted. And that is why i say "crap".
Should flight checking work in the UK? It never has for me yet. If she scans email for flight numbers that suggests this service is automated. Correct?
Cortana is promoted in such a way to suggest she is intuitive but I see very little evidence.
I joined Insider recently and upgraded to Win10, just to see if Cortana works better, but i get the same lack of dependability that I have already described.
Sorry, I want to love Cortana but so far she is a big disappointment.
