Can't use VoLTE and Wi-Fi calling on Xperia with latest firmware

Hi

 

On my Xperia X Compact (F5321) using the latest firmware I can't use VoLTE anymore.

 

It worked on Android 7.0 but after the update to 7.1.1 it won't work.

Tried with the official firmwares 1305-0029 (Customized CH / 34.3.A.0.194 R4D) and 1305-3835 (Swisscom CH / 34.3.A.0.194 R3D) without success.

 

 

I write this here in the general discussion as someone using a different device may having the same behaviour and a solution for this?

VoLTE and Wi-Fi calling is working again, after installing the Update 34.3.A.0.206.
