Just signed in to your service, looks really good!
So I signed up on my Mac (username, password, personal data, picture etc.) everything fine (only hard to find my way from the community page back to the weather map).
And then I downloaded the app for my iPad Mini and tried to login (with the same email and password I just registered) but it said that email and password was wrong.
So I created a new account on the iPad with exactly the same email and password as on the Mac, and I was accepted og logged in. So now I have 2 accounts, or?
Does not seem right, does it??
