Kind of a weird one. I have this new app called Hidrate, that works with a water bottle. But the App does not show up in my iPhone's Settings. Specifically within Settings > Notifications. The app just does not exist, but all my other apps do. This seems to be causing issues with the App sending me notifications to drink water as, and I even tried reinstalling the App, as well as resetting Location and Privacy within Settings > General > Transfer or Reset iPhone > Reset > Reset Location & Privacy. No luck
