Not getting notifications on one of the iPhones

[PGalore]

I don't know since when but just found out I hadn't been receiving push notifications on one of the iPhones. I'm pretty sure this started last week.

I haven't changed my settings both on the phone and app. iOS and the app are up to date.  I went through this article as well.  https://kb.arlo.com/1099161/Why-am-I-not-receiving-Arlo-notifications-on-my-iOS-device

I also logged out and back in, removed and reinstalled app, and restarted my phone.

Notifications are still sent to Galaxy S23 and iPhone 14 but not to iPhone 12. What can I do to fix this?

Do all the device see the "Feed" option at the bottom of the Arlo app?
