My husband and I both have the same issues on XR and 12 iphones. We noticed after 15.2.1 update. Stock app top business stories newsfeed only seems to be there after phone is turned off and then back on and then goes away shortly after until the next reboot and then briefly appears again. Apple support was of no use when I phoned them. They told me it was because we don't subscribe to apple news+. I think that's total bs. The news feed is from apple news (which I can view on the news app) not apple news+ and why would it be there after a reboot if I need to subscribe and am not signed up for a free trial? And you can't update the stock app under apps. Apple, please fix. This did not seem to be a problem before 15.2.1 upgrade.
