How can I disable the xfinity push notifications that are just advertisements.

I'm on Android also but unfortunately don't have those options shared above. There seems to be no way to turn off push notifications in the app - I can only turn off all notifications at the system level. And yes, I've followed all the advice above but I simply don't have those options available to me under Account Settings. I just updated my app too trying to figure this out and no luck. Has anyone reported Xfinity to the FTC for not allowing users to opt out of marketing?

I just received a notification on my Apple Watch (running the '26 OS) that xfinity is offering a discount on a samsung galaxy. The latest of many xfinity annoyances. I too have been through the xfinity app settings only to find that there is no way to turn off marketing or promotional notifications. I have unsubscribed from all marketing on the website and I still receive these annoying push notifications on my phone and watch. There's no way to disable them without blocking all notifications, including from xfinity home security (since they've moved everything to the xfinity app, instead of the former home app). 
Xfinity "engineers", if you need help figuring out what iOS APIs to invoke to add a radio button to disable marketing/ads, I can help you. Or just ask an LLM. In any case, stop this nonsense ASAP. As others have pointed out, you're violating Apple's TOS and risk being penalized on the app store with update reviews etc.

MASSIVE XFINITY FAILURE!!!!!!!!!!  So many false instructions which don't work or are just AI [Edited: "Language"].  What a joke calling this "support".
Seems the only fix is to turn off ALL push notifications.
