im probably late to the party here, but I bought the Tab S9+ and registered for Disney with no issue. This is my second free year as I registered last yr with my Z Fold 4 free offer through Boost. You have to let your paid subcription finish first by cancelling. Then make sure you do not use a browser with pop ups suppression. That was my mistake last yr. However this yr I let my subscription finish then Boost accepted my Tablet and gave me the code. I then signed back into Disney using my same sign in details and it accepted the code and I now have Disney again free. Hope this helps cheers
