Samsung Galaxy S8 Wifi Calling

Has anyone found a solution to the Wifi calling issue with the Galaxy S8? I have read several threads with many reporting the same issue I am having---keeps turning off by itself and constantly sending notification to turn it on, even when it appears to already be on.

I cannot get any calls while I am at work and I missed a VERY important one last week.

It is obvious that this problem occurred after the last system update. I have tried all of the so called "fixes" that were posted by verizon on the other threads. Please let me know if Verizon is working on this or if I need to change carriers. I cannot stay without a phone.
