New Wifi calling not working on xiaomi.eu_multi_MI10Pro_20.3.26_v11-10

I am using the Mi 10 Pro with Vodafone Germany on "xiaomi.eu_multi_MI10Pro_20.3.26_v11-10". Wifi calling is not working. If VOLTE is activated all incoming calls shown "unknown caller". I understand that the Profile "Germany-VoLTE-Vodafone" needs to be updated. Sub0 und Sub1 needs to be changed to ACTIVE. Is it possible to update the ROM accordingly? Other than that, the Rom works perfectly, good Job!

It seems there is a solution to the problem in this description: https://forum.xda-developers.com/poco-f1/how-to/guide-activate-vowifi-wlan-call-t3871263 . But I do not want to root the Mi 10 pro because I might have problems with Google pay and banking apps. Is it possible to apply this Mod in future ROM updates?

I second that. A working VoWifi without root in MIUI 12 would really be great.

Once you activated sub0 and sub1 you can unroot your device. I have tested it on my Mix3. I also wiped system, internal storage, flashed some different roms and its still working!

If you update your rom (beta or stable) VoWifi and VoLTE persists.

I only have the VoWifi icon in stagusbar, bit both are working as seen in call history
