I am on an iPhone 8 Plus. I've been having an issue since the first IOS 14 update and the latest still hasn't corrected it. Wifi keeps dropping. The settings tell me I am connected to a wifi network, however the phone thinks it's still using my LTE data coverage which is sparse at my house and very slow. I've tried the airplane mode trick with no success. Rebooting the phone will sometimes reconnect me but I don't stay connected.
