Fast Return to 5G getting failed because UE not recieving Mobility Command

Dear Experts.

Fast Return to 5G is getting failed.

As per eNB logs mobility command is sent to UE but UE is not recieving mobility command (have checked in UE logs).

Any suggestions?

What about SIB24?

SIB24 is active.

If it is Samsung to Jio
Set Volte_nr_restrict_option and emergency_nr_restrict_option to TRUE
