iPhone 11 Pro AT&T wiFi usage not staying on, setting is!

Has anyone else noticed this? I'll check my phone, and even though the Cellular setting shows AT&T WiFi on, if I check the Control panel top left corner, it does not show AT&T WiFi. This will even be in my basement (sketchy Cellular, but next to my 1GB WiFi router). So I do the trick - turn on Airplane Mode with WiFi still on, wait, and AT&T WiFi comes back, then I turn Airplane mode off. Later (hours, maybe a day) I'll notice AT&T WiFi is off again. It may be when I go out of the house, which is not often these days; I'll have to watch it more closely. But is anyone else seeing AT&T WiFi turn off even though the setting is on? I guess there is nothing I can do other than just keep turning it back on...

Mine automatically switches to AT&T Wi-Fi if cellular signal is low.

I don’t understand this post. It switches back and forth based on cell signal strength and if you are on WiFi.

Right - but with lo cellular signal and very strong WiFi shouldn't it be on WiFi?

For me it stays on wifi calling with 1-2 bars consistently. If I have 3-4 bars consistently then it usually prefers to stay on cellular. This is complicated by the fact that LTE could have a different signal strength over 3G, for instance at home right now I get 1-2 bars over LTE but I can switch it to 3G and it's at full signal. It still prefers wifi calling over even strong 3G, and especially over weak LTE. But at work there's strong LTE and it hates using wifi calling there. I guess there's a judgement call about what the highest quality voice call combined with the most mobility it can get, for instance it doesn't like wifi over LTE calling because wifi might cut out if you move around, and it likes LTE over 3G because of the higher voice quality even with LTE signal being potentially lower.

You kind of have to use Airplane mode to force wifi calling, as far as I know. You can disable wifi calling but not force it if cellular is on. Similarly some iOS software update took away my ability to turn voice over LTE off. It hasn't been a problem for me but there could be places where LTE is better for data but 3G is better for calls (you can only turn LTE off entirely but not turn off LTE calling only, but there used to be that option).
