cxj05h , via OnePlus 6T , Nov 15, 2019 : I haven't found a clear answer for when weather appears above the fingerprint sensor. under contextual info for ambient screen settings it's just a toggle. I have seen calendar alerts and information about what song is playing etc but weather seems to have no logic. however the weather is probably something that should always appear unless it's forced out by more relevant information. my weather only appears at around 4am.
