Having the same issue.
S21 G996B/D
Was on T-Mobile.
June update ruined the phone (was unable to receive calls after the update like many, many others).
Flashed May Stock Firmware, problem solved.
Then I changed my carrier to AT&T 2 weeks ago and now my S21 does not even have settings for WiFi calling...it's gone, vanished, like the S21 doesn't have it (it does...). I used it before.
This is the craziest thing.
