Mobile data switch not working in s23 ultra

[Vvkps]

Hi if I am using mobile data of Sim 1 and got call on sim2 mobile data not work.

Tough i have already enabled data switching and backup calling. 

Can anyone advise?

Bro you can't control your sim 1 data which sim 2 have a call
Plz understand

This was working on any xiaomi devices, I guess you didn't get the question.... Also what's the use of data switching and backup calling option?

Also I am not saying Sim 1 should control data of sim2, I want data should be switchable on both Sim as per call occurance

In this case it only works for default mobile data Sim not the secondary one so switching not working
