About a month ago, HBO was removed as a Prime Video Channel subscription option. This was a decision made by HBO to force all subscribers to subscribe directly. This prevented all new subscriptions through Prime Video Channels, but those that were already subscribed have been able to continue to access HBO content. Now we know that all existing Prime Video Channel subscriptions for HBO will be canceled on September 15, 2021.

An email sent from Amazon to customers subscribed to the HBO Prime Video Channel reads as follows:

Hello,
We’re writing to let you know that HBO has decided to leave Prime Video Channels. As a result, your HBO subscription will end on Sept. 15, 2021, at which time we will cancel your subscription and issue a pro-rated refund for any remaining service from your last billing cycle. No action is needed. With Prime Video Channels, you can choose from 100+ channels. Plus, thousands of movies and TV shows like the recently released Cinderella, Tom Clancy’s Jack Ryan, The Boys, The Marvelous Mrs. Maisel, and Thursday Night Football are yours to watch with Prime at no extra cost.

Happy watching,
Prime Video

As stated in the email, those currently subscribed will be issued a refund for the remainder of their current billing cycle. This only affects customers subscribed through Prime Video Channels, not through HBO directly. If you’re unsure whether or not you’re subscribed directly or through Prime Video Channels, visit this page to see if an HBO subscription is currently listed in the “Channels” tab on your Amazon account.

If you’re subscribed to HBO through Prime Video Channels and want to keep your subscription, you will need to subscribe through HBO directly. It doesn’t matter if you do so before or after the September 15 cancelation date, but it’s probably best to wait until after, so that there aren’t any dates that overlap, where you’ll technically be paying for 2 simultaneous subscriptions. Unfortunately, HBO has not created any kind of transfer option, so you will lose all settings and history associated with your current account, such as watch history, video progress, and watchlists.
