I don't know why I am continually checking for a fix here. I doubt it will ever show up since everything else is going wrong. Fitbit broke, car dead, s8 wacky.
First Calling Plus works well I have used it a several time second if folks are having call issues make sure the Wi-Fi Calling part is Off and LTE Calling is the only one turned On. Also if your want to use Wi-Fi Calling try having it On and LTE Calling set to Off to see if that helps for those that use Wi-Fi Calling.
