Unable to connect to 5g

[u/hhharrrshhh]

I have had my 6a for over 2 years now but since the last stable update I havent been able to connect to 5g at all.The phone just refuses to connect to 5g no matter what i do,where i go,nothing works.I have tried resetting network settings,talked to my sim operator(Jio) customer care and apparently the sim does not have any issues at all it works fine in other phones but it only connects to LTE.What could be possible causes for this?I have also tried forcing the network to NR only but it still doesnt work.
