They still do list it as being available during the Recharge flow of the MyJio app though. In the Recharge flow, the 'View Details' option under each plan does list 'Jio Cinema Premium' as one of the 14 available OTTs for all 300 Mbps & above plans. It is listed for all of Annual, Semi-Annual, Quarterly and even Monthly plans. It is not listed as being available only for the 150 Mbps (only free content) & below plans.
Did they forget to remove it from here?
