There is no option on the new OS to show which Sim you are receiving the call. however, top right side, it will show which sim you are receiving the call. the method I am using to differentiate is by setting two different ringtone for each sim

yes.. because phone has to configure all.. so it's normal..

resetting phone also didn't help. hence uninstalled and reinstalled the apps which helps

the only way is to uninstall and reinstall the not working apps which will resolve the issue

these apps needs to reinstalled after the update.. all my data in Samsung Pay also got removed
