I bought Disney + yesterday and it went well but when I wanted to change my device from the pc where I bought it to the laptop, disney + asked me to buy the subscription on the laptop after registering as if I had to buy it 2 times?
Perhaps you pressed Register instead of Login?
normally you should be able to log in easily.
No, I register and it says: "Completion of the subscription" but on my pc I can watch the snapshot and when I click on it I want to buy a subscription
Do you have to confirm any confirmation email?
Don't think so
