"Wifi on iPhone cuts out: Hi all Lately I have found that when my iPhone 12 turns off (not completely off!) it loses the Wifi and reverts to 4G. When I turn the phone back on it eventually picks up the wifi again. Obviously I’m worried how much data is being used when it’s gone onto 4G. I have cut out all but the necessary apps which run in the background but I really need this sorting asap. Any thoughts? Many thanks for any help. p.s. I am running iOS 14.8 on my iPhone 12"

Try disabling Cellular, and using Wi-Fi instead, seeing if that makes all the difference.
