@adystan262 That’s got nothing to do with EE thats an iOS update. Have you tried resetting the network connection on the device? It’s in settings/general/transfer or reset iPhone/reset/reset network settings. iOS 17.2.1 was released 19th of December and 17.3 is about to be released. Probably 22nd of January.
