If you’re unable to upgrade to purchase the TV Stick Only offer, it’s because this offer is only available after your current plan expires. You must wait until your existing subscription ends before you can upgrade and buy the offer. To check your plan’s expiry date, visit Account Settings > Subscription Details. Cancelling your current plan does not allow an early upgrade. If you continue to experience issues after your plan has expired, please try restarting the app or contact customer support for further assistance.
