this is the free version, for english one needs to purchase the premium subscription. I had a chat Jio folks on this, you may want to reconfirm if the understanding has changed somewhat.
They have been including Jio cinema in the bundled ott list in fiber and mobile prepaid plans since the beginning because jio cinema used to exclusive to jio users till last year.
This is now completely misleading and false advertising because we get only free version of the app bundled with these plans and free version is now available to everyone without any jio plan or jio sim. They probably have to update this.
I had made a post regarding this exact confusion on another thread saying they have to stop including Jio cinema in the bundled ott apps because they're completely misleading and false advertising
