Same here on the new update available popup.
Also today I had a more alarming issue: the phone app became unresponsive; I couldn't move to any of the tabs and my favorites weren't showing the contact pictures. Tried quitting and restarting the app several times with no improvement. Turned off wifi calling (I'm on T-Mobile and aware of the wifi calling issues, though it's been working for me); again nothing. Rebooted the phone and the first reboot didn't help, but a second one finally did. Has anyone else seen anything like this?
By the way, I had done the "reset network settings" earlier this week after the latest beta install. I guess I could try doing that again. I haven't tried "reset all settings" yet. Thanks for any suggestions.
