I have not switched on my Jio STB for over a couple of months now, I guess. I don't use it. Instead, I have downloaded the necessary apps in my TV, and have logged into them with the Jio Fiber Registered Mobile Number. Most of the subscriptions work, except for a few. For example, Voot. Most recently, I believe SonyLIV lost the subscription too. I have to check it again. I don't use SonyLIV for the most part, and I saw that the Jio Fiber complimentary subscription was no longer working in it when I checked it after an app update, a couple of weeks back.
So to reiterate, I have not tried it as I was not looking forward to using the Jio STB, at least anytime in the near future. I was just spitballing there, just trying to help you out
