I received the September security patch last night (N970U1UES4CTH1). When I’m at work, I have to use Wi-Fi calling to get texts or calls since I am on the ground floor where there’s no signal. I’ve never experienced any issues with this, however since this morning, I’ll randomly get a notification stating “Wi-Fi calling preferences updated to optimize network experience”, and suddenly I can’t call or text anymore. I go into the settings and it’s switched it to “Cellular preferred”. If I change it back to Wi-Fi preferred, it’ll continue to work for an hour or so then it switches it back again following the notification.
Any way I can stop it from making changes? This is really frustrating, I feel that I should have control over my Wi-Fi calling preferences.
