It seems that ever since VZW updated to allow Wi-Fi calling, in the last two beta's (4&5) my VZW wi-fi signal comes and goes. It doesn't seem to matter if I'm at home or work or on a public wi-fi. My thinking is that it should grab and hold onto the setting until you're out of range from the wi-fi modem, no? Anybody else see this? Or is this how wi-fi calling works on all the carriers? I've sent in two reports to Apple, once on beta 4 and once on beta 5. Not sure if this is an Apple issue or VZW.
