Airtel — volte issues on my sim

Hey team, back when airtel volte services started rolling out in my region (Odisha, bhubaneswar), i was able to use volte services. From a few months volte isn't coming on my sim. My father and my friend uses airtel and they've volte enabled on their sim. I've a jio sim too and it works flawlessly.

P. S. No network issues or calling issues, it's just that volte service isn't coming. I was a member of the beta roll out and one of the first members to get volte.
