@idefix37 Thanks - it was not so clear how to reach the login button from the iphone app - but have now found it.

@Korina Similar to others, i bought the premium subscription on windows, understanding that it would work on all devices. But when i try to access on the iphone device app, i cannot link the order number.

Is there any way to link a windows purchase to an iphone app? If not, it would have been good to make this clearer in the subscription information and not say the subscription works on every device.
