It got automatically added in my homescreen. I searched in jio store as well and it is available out there. With regards to plan, I am already having Amazon Prime access and logged in with that account. Not sure in which plan they are going to bundle it.
Yes. It has been added.
But its subscription is not yet bundled with the plan. I am on a silver plan and when I opened it, it asked me to login; unlike other OTT apps where the subscription was automatically activated because of JioFiber.
Don't know if they will bundle it with silver plan or with higher plans.
