After the recent system update, I started receiving prompts on my Galaxy S8 about needing to update my emergency address for wifi calling. Each time I tried, there was a prompt at the end telling me that the address could not be updated currently, telling me to try again later. I tried several times over the next 2 hours and kept getting the same message. I tried restarting my phone, but that did not help. At this point, the notifications asking me to update the address are no longer appearing.
I tried following instructions for updating the address based on https://www.verizonwireless.com/support/knowledge-base-201651/ and other pages, but the settings in those instructions do not match what is available on my phone.
