When your hbo max just doesn’t work.

If you don’t want to watch.
-old accounts having the same cell phone as the new account will cause issues.
-auto fill on your cell phone not being updated, for example when you move address and never updated your information or made sure the xfinity id matches your current account information the old information mixed with the new accounts will cause issues and just not work.
- trying to create an account straight through hbo while having this issue might cause the same issues. Cause hbo will use a private email instead of your Comcast or phone identity. Then it will count as a second subscription.
