After updating on morning of 23 April 2020 I was unable use WiFi Call. WiFi Call is Enabled and tested on few other WiFi networks.

Never happened before after an update. Also for the 1st time ever after this update, phone lost all APN setting which I solved.

I have used following:

SAMSUNG_USB_Driver_for_Mobile_Phones_ver_1.5.65.0 (driver for windows)
Odin3-v3.14.4  (software for adding firmware)
G9700ZHU3BTC3_G9700TGY3BTC3_TGY  (March 1st firmware - only for S10e)

 

After reinstalling firmware don't update or you loose Wi-Fi Call.

 

I added link earlier but post was deleted.

I've noticed after the update as well Wifi Calling for me works sometimes, other times it doesn't.  Shutting off Wifi and going to LTE sometimes lets things go through, other times I have to restart the phone.

 

Also getting Sim 2 Not Allowed error messages constantly. It will either come back on its own or I have to restart the device.

 

Clearly whatever they did to the networking coding for the update made the coding more of a mess not less. I just don't understand how a major company who has the unmitigated gall to be charging what they are for devices, can't get the basics down of coding.
