thats why, AT&T Need to know their new business, in/ out.
had a particularly frustrating experience when the HBO Now app on his Samsung TV automatically changed to HBO Max but locked him out, claiming his internet service provider was not a provider of HBO Max. Since HBO Now is no longer on the Samsung App Store, he lost all access to HBO and was told by customer service he needed to cancel.
Anecdotally, I could not download Max to my iPhone until I deleted all HBO apps off my phone first, since it seemed to think the apps were the same coming out of the App store and urged me to “Update” instead of install, despite the update button doing nothing. If I were a standard HBO customer, I would likely have assumed this was not a bug, but a feature and believe that Max and Now shared all the same content (which they do not).
