@Ketan Kr, @Apiyush265, @R0userIf someone calls me and if I don't answer that call then call management system should show a notification for the missed call.                                  BUTAfter updating to MIUI on 15th of August 2019 I found that the  inbuilt call management system is not showing me any notification for the missed calls.I checked all the settings of call management along with notification settings and all the settings are enabled but still if someone calls me and cuts the call or if I don't answer the call at that time then when I unlock the phone then thete is no notification for missed call, which was working fine before updating to 10.3.4.
I did factory reset also re-download and reinstalled whole update through Updator app but no change.
