When I originally got the wifi calling update, I was ecstatic, because at work I don't get an LTE signal. I always have to put my phone in airplane mode, but I could finally make and receive calls over the wifi network. It was phenomenal. But there's been another update since, and now, it won't do wifi calling in airplane mode anymore. Anytime I try now it says "cannot make or receive calls in airplane mode." What happened? I need to be able to use my phone here, this is absurd.
