I managed to sort out my boost for Disney +, but missed to save the code. Now when I try to get access again, submitting comes with a message that the code was already issued. Any way to get the code again or is it somewhere stored?
If you didn't use the code i.e activated it by using it then Samsung should be able to help with this if you call Samsung Support for your particular region. They may need to get Samsung Promotions involved.
