They are least bothered about medium they watch their content from. Do you really think anyone cares which platforms they watch at public place?
JioCinema is a first time streamer of IPL and a relatively new streaming player (after merging with Viacom). So they are required to make people aware with ads. You are saying as if Hotstar never aired any ad after getting streaming rights for the first time after Times Internet.
Went through it. People are praising their different and unique offering.
Jokes aside! People are something facing streaming issue which are resolved after every updates. I till now personally didn't face any streaming issue. And I am streaming using mobile data.
