No Internet acces during a call after upgrade to OneUI?

[Android Central Question]

After upgrade to OneUI on Note 9, I haven't acces on Internet during a call. I tested during a call with Speedtest and there is a little trafic 0.2-0.3 Mbps. Practically nothing works.
I use a Vodafone network that they use voice on 3G and data on 4G. I tested other network (DIGI) where the voice and data works use the same networks 4G and there averythink is ok.
Any idea? Tk.

Sounds like an issue with the Vodafone network since it work on the other network.
