As the subject says, after an update my wifi calling stopped working. After a lot of searching on google this appears to be a common problem.
An example of what I've already tried to fix it:
Turning off, then re-enabling wifi calling.
Rebooting the Phone
Resetting network settings
Factory data reset: This worked, temporarily. However after the phone finished updating itself and before I could install any apps it stopped working.
