Is anyone having jio network issues in Redmi k 20.

Is anyone having Network issues in Redmi k20 after updating MIUI 11. In my K20 whenever i put jio network sim either in Sim 1 or Sim 2 after few moments the network is gone/unavailable. While other network like idea, vodafone works well but jio not working. After reboot also the jio network doesn't comes. It happens every day most of the time. Any of the jio network network sim happens the same. The issue is with the software. Kindly resolve the issue else I'm seriously not going to use any of the Redmi phone lifetime. After investing 24000 in flagship type phone u will face this type of issues daily. Then what's the use of buying this type of useless phone. Always sending reports and bugs is doesn't help at all. No resolution is being provided. Only show off of MIUI 11. Totally waste update and battery backup also decreased with this network issues. Manually network search also doesn't works. Always failed in searching of jio network manually.
